Error messages explained

When something goes wrong, Stream UI Fun Studio tells you in plain words what happened. This page lists those messages, grouped by where you see them, with what each one means and how to fix it.

Find your message fast

Press Ctrl + FCmd + F in your browser and type a few words from the message you see.

Words in italics stand for something the app fills in, like your file name, a pack name, a platform (Twitch, YouTube…) or your handle. If you’d rather start from what’s going wrong than from a message, see Troubleshooting. A message you can’t find here is probably one of the general messages at the bottom.

OBS connection

These appear in the Add to OBS window (the one that opens when you click Add to my stream with OBS as your streaming app). While it isn’t connected, the window checks on OBS by itself every few seconds, so it often moves on as soon as you fix the problem.

Headings in the Add to OBS window

You see	What it means	What to do
OBS Studio isn’t installed	The app can’t find OBS Studio on this computer.	Click Get OBS Studio, install it and open it once. Using another streaming app? Click Another app for its steps.
Open OBS Studio	OBS is installed but not open.	Start OBS. The window notices on its own, or click Check again.
Turn on OBS’s connection	OBS is open, but nothing answers at the address the app uses: its WebSocket server (the switch that lets other apps talk to OBS) is off, or it listens on a different port (normally 4455).	In OBS, open Tools → WebSocket Server Settings, tick Enable WebSocket server, click Apply, then click I’ve done it. You only do this once. Already ticked? Set Server Port to 4455 in the same window, click Apply, then I’ve done it.
OBS needs its password	OBS protects its connection with a password.	Click Auto-detect password. Or copy it from Tools → WebSocket Server Settings → Show Connect Info in OBS, paste it and click Connect.
Can’t reach OBS	OBS isn’t answering the app. It may be busy or frozen, the app couldn’t tell whether OBS is running, or the Server address points to a computer that doesn’t answer.	Click Auto-detect password: it also picks up a changed port. Still stuck? Restart OBS, then check Tools → WebSocket Server Settings: the server is on, and the Server Port matches the end of the Server address in the app (normally ws://127.0.0.1:4455).
Update OBS Studio	Your OBS (or its WebSocket connection) is older than OBS 28, which the app can’t talk to.	Update OBS Studio to version 28 or newer (it’s free; Get OBS Studio opens its download page), then try again. Until then, use Add it manually.
OBS is on another computer · Adding automatically only works when OBS runs on this computer. Use “Add it manually” instead.	The app is connected to an OBS at another address. Adding automatically only works with OBS on the same computer, so Add to OBS is greyed out.	Use Add it manually. For a two-PC setup, save an HTML folder instead: see Add to OBS by hand.

Messages under the password box

You see	What it means	What to do
Couldn’t find OBS’s settings on this computer. Paste the password instead: in OBS open Tools → WebSocket Server Settings → Show Connect Info.	Auto-detect couldn’t find OBS’s settings on this computer.	Copy the password from Show Connect Info in OBS, paste it and click Connect.
Found the settings, but OBS didn’t accept them. Paste the password from Tools → WebSocket Server Settings → Show Connect Info.	The app read OBS’s settings, but still couldn’t connect with them (the password may have just changed).	Copy the current password from Show Connect Info and paste it.
That password didn’t work. Use Auto-detect, or copy it again from Tools → WebSocket Server Settings → Show Connect Info.	OBS turned down the password.	Click Auto-detect password, or copy it again. Watch for extra spaces.
OBS wants a password. Use Auto-detect, or paste it from Tools → WebSocket Server Settings → Show Connect Info.	OBS needs a password, but none was given (for example, you clicked Connect with the password box empty).	Auto-detect it, or paste it.
OBS isn’t answering. Check that it’s open and its WebSocket server is turned on.	Nothing answered at the server address.	Open OBS and turn on its WebSocket server (see Turn on OBS’s connection above).
OBS took too long to answer. Make sure it isn’t busy or frozen, then try again.	OBS is there but slow to respond.	Wait for OBS to settle (or restart it), then try again.
The OBS address must look like ws://127.0.0.1:4455.	The Server address you typed isn’t in the right shape.	Type it as ws://127.0.0.1:4455 (change only the number at the end if OBS uses another port).

For the full walk-through, see Connect the app to OBS.

Adding to OBS

These show up when you click Add to OBS (or Update in OBS), Play now or Refresh. If the app can’t connect to OBS at that moment, you get one of the messages under the password box instead, like “OBS isn’t answering…”.

You see	What it means	What to do
OBS said no to that request. Try again, or add it manually.	OBS refused what the app asked, for example because the scene was just renamed or removed.	Close the window and open it again so the scene list is fresh, pick a scene and retry. Or click Add it manually.
OBS was closed. Open it again and retry.	OBS closed while the app was talking to it.	Open OBS, then try again.
This source isn’t in OBS any more. Add it again.	The element’s source was deleted in OBS.	Click Add to my stream to add it again.
Add this element to OBS first.	The app doesn’t have this element down as being in OBS any more, for example after its source was deleted there.	Add it with Add to my stream first.
Adding automatically only works when OBS runs on this computer. Use “Add it manually” instead.	The app is set to talk to OBS on another computer.	Use Add it manually, or see Add to OBS by hand for two-PC setups.
Your OBS is too old to connect. Update OBS to version 28 or newer, then try again.	Your OBS is older than version 28.	Update OBS Studio.
Click Refresh in OBS (editor) or Refresh in OBS (card)	Your change is saved, but OBS couldn’t be reached to show it.	Open OBS: the app refreshes waiting elements as soon as it reconnects. Or click Refresh in the editor.
Couldn’t copy. Select the text and press Ctrl+C instead.	The app couldn’t put the text on your clipboard.	Select the text yourself and press Ctrl + CCmd + C.

Downloads

These appear on a progress card at the bottom right of the window (or next to Download in the TikTok LIVE Studio guide), in a pop-up message, or in the More formats window.

You see	What it means	What to do
Video export needs a part of the app that’s missing. Reinstall Stream UI Fun Studio to fix it. (Under the Download button: … Reinstall to fix it.)	The part of the app that makes videos is missing. Download is greyed out, and the video choices in More formats are too.	Reinstall Stream UI Fun Studio (see Download and install). Add to my stream and the HTML folder still work meanwhile.
The video encoder stopped unexpectedly. Try again, or pick another format.	The video maker stopped partway.	Click Retry, or choose another format in More formats.
The video couldn’t be saved. Check the folder still exists and there’s free disk space, then try again.	The file couldn’t be written: the folder is gone, the disk is full, or the file is open in another program. You also see this when an HTML folder can’t be saved.	Free some space, close any program using the file, or save to another folder.
Recording this element took too long. Try again — closing other heavy apps can help.	Recording took longer than the app allows, often because the computer is busy.	Close games or other heavy apps, then click Retry.
This element couldn’t be recorded. Try again, or reset its settings.	The element stopped working while it was being recorded.	Click Retry. If it fails again, try Reset all changes (see Make copies and reset changes).
Some export settings aren’t valid. Check the format, size and length, then try again.	The chosen options don’t work together. This is rare.	Pick different options in More formats.
This installation can’t write WEBM videos. Pick another format.	The video maker on this computer can’t make that format (WEBM, MOV, MP4 or GIF). In More formats, such a format is greyed out; point at it to see Not available on this computer.	Choose another format in More formats. If none work, reinstall the app.
That file isn’t there anymore.	You clicked Show in folder, but the file was moved or deleted.	Look in your Videos folder (videos are saved in Stream UI Fun Studio there unless you picked another place), or download the video again.
Saved “file name” · No sound played, so it’s silent	The video is saved. Sound was on for it, but the element played no sound while it was recorded.	Check that a sound is picked under Advanced → Effects, then download again.
This format can’t include sound on this computer.	Shown in More formats for a format that can’t carry sound here, so that video is silent. (GIFs say GIFs have no sound.)	Want sound? Pick WebM, MOV or MP4 if one of them shows a Sound switch.
No sound is picked for this element, so there may be nothing to hear.	Shown under the Sound switch in More formats: the element has no sound chosen.	Pick a sound under Advanced → Effects first, or leave sound off.

Picture & counts

Channel and element pictures

These show under the picture in the Your channel panel, or as a pop-up message in the editor.

You see	What it means	What to do
That picture is bigger than 20 MB. Pick a smaller one.	The file is too big.	Use a smaller picture (a screenshot or a resized copy works).
That file isn’t a picture. Pick a PNG, JPG, WebP, GIF or SVG.	The file isn’t an image the app can use.	Pick a PNG, JPG, WebP, GIF or SVG file.

Follower counts

These show in Followers & subscribers in the Your channel panel: under a platform’s row, under the Fetch counts button, or under the Auto-fetch once a day switch.

You see	What it means	What to do

When you drop or pick a .zip

These appear in the panel that opens after you drop or pick files (or as pop-up messages when that panel isn’t open). Each file that didn’t work is listed with its reason. If some files worked and others didn’t, the panel says You’re all set! (or Almost there!) and lists the files that didn’t work underneath.

Each file that didn't work is listed with the reason.

You see	What it means	What to do

“file” isn’t an unlock file for the app. Drop the .zip you downloaded from Gumroad after buying (or the “- for Stream UI Fun Studio.zip” file inside it).	It’s a different file or folder, for example one of the files for OBS or StreamElements from inside your download, a product made only for other streaming apps, or Gumroad’s Download all .zip of a set.	Drop the .zip you downloaded from Gumroad. If you unzipped it, drop the file inside it whose name ends in “- for Stream UI Fun Studio.zip”. Bought a set? Drop each product’s .zip. Lost it?

Right-click it, choose Extract AllDouble-click it in Finder to unzip itRight-click it and choose Extract Here (or Extract), then drop the folder (or use Choose a folder).
“file” holds too many packs at once. Drop them in smaller groups.	One .zip or folder holds more than 20 packs (the app takes the first 20), or more than 100 zips and folders to look through (then it takes none).	Unzip it and drop the packs that weren’t unlocked in smaller groups.
“file” is larger than a pack can be. Download it again from your Gumroad library and drop the new file here.	The file is far bigger than a pack should be.	Download it again.
Pack or file doesn’t come from Stream UI, or it was changed after it was downloaded. Download it again from your Gumroad library and drop the new file here.	The pack’s seal is broken: it was changed or damaged.	Download a fresh copy.
