Dear all,

A colleague and myself have installed the latest Mattermost Desktop (5.1.0) last week on two independent Mac computers – since then, the app does not work anymore. When clicking on a channel, the content does not appear (the app indicates it is “loading” the content, but nothing happens).

The connection to my account is still there, since I continue to get notified about new messages (but then cannot open them). We have had to revert to the browser version of mattermost to keep using it.

Does anyone else have this problem and – ideally – a fix for it?

Best,  
Jan

I am facing the same problem, clearing the cache and reloading does not help.

Hi,

We’ve faced a similar issue and it was because of a bug (see [5.1.0 error.team\_not\_found message when trying to change channel · Issue #2133 · mattermost/desktop · GitHub](https://github.com/mattermost/desktop/issues/2133#issuecomment-1138825012) ).

The problem was the configured URL in the desktop app for the users that have the error includes the teamname, like `https://mm.ourcompany.com/ourteam`, instead of just `https://mm.ourcompany.com`. After fixing this, it worked fine.

Hope it helps.

Regards,  
Ezequiel
