Summary
Images not loading in desktop app after latest update
Steps to reproduce
Using Mattermost Desktop App v5.7.0 on Windows 11
Logged into self-hosted Mattermost server (v9.5)
Uploaded images in a channel
Other users can see them, but I see a broken image icon
Expected behavior
Uploaded images should display normally in the chat window
Observed behavior
Images appear as broken or missing. No preview, just the broken image icon. Works fine in the browser, only broken in the desktop app. No error message shown.
9.5 is pretty old. I’d highly recommend updating to 9.11 and then 10.5 Release Policy - Mattermost documentation
5.7 is not supported for 9.5… see Desktop Releases - Mattermost documentation 5.8, 5.9, and 5.10 would probably resolve this.
Hi. I had the same problem. Updating the desktop app partially solved the problem. But it still sometimes reproduces on different systems. Updating the server to 10.5.2 also partially solved this problem. It reproduces less often, but other problems were added. I can conclude that version 9.5.6 works more stable than 10.5.2
