Tray icon won't launch after update

Hello.
Im using Duplicati for a while now, mainly as a Docker Container but also tried it on a few machines as a Windows or Linux Service.

I was searching for the same solution an the OP and the closest one was this thread.

After long searching, trying and configuring, i reinstalled my Mint VM bc i thought it could be a Cinnamon thing and tried the 2.1.0.110 Canary of Duplicati.
And: the tray icon shoes up with the startup parameters “–no-hosted-server --webservice-password=XXX” and it also opens the webui!
Only thing is that it always resets the webui color to light mode, but somehow this was my solution.
Probably this will be the fix in future stable release, but i wanted to take some words on that after i was frustrated months long.

Actually that make sense due to these fixes

v2.1.0.109_canary_2025-02-11

Fixed multiple issues with TrayIcon state

and one of those was the --no-hosted-server case that’s being discussed.

v2.1.0.5_stable_2025-03-04

This is an update release to 2.1.0.4, fixing critical issues.

and maybe this issue wasn’t critical enough. In any case, it’s not in release note.

“Duplicati.GUI.TrayIcon.exe –no-hosted-server” not working

has a workaround for the --no-hosted-server setup that runs a Canary (so less trusted, but good enough for status and control) TrayIcon and the 2.1.0.5 service.
