Unable to connect via Desktop App

Hello ,

It seems I have the same problem in here : Unable to login via Windows app (ok on web version) - #8 by agriesser

I don’t manage to connect anymore with the desktop app (I didn’t have the problem before) but I can connect through the browser

I’m on Ubuntu. I tried to delete Mattermost directory in ~/.profile but it didn’t help

Here’s what I get on Mattermost Console :

Thank you for you help!
