Are you running 2 or more parallel instances of UniGetUI?

[redactedscribe]

I just ended the only process of WingetUI.exe (and looked for any mentions of UniGetUI) and launched the program again. Still the error occurs.

[marticliment]

Do you know if you use any program that uses the port 7058? Can you check if your firewall is blocking localhost:7058

[redactedscribe]

My firewall does not block any localhost I believe.

I just checked and I do see a local port in use for 7058 bound to ensserver.exe (EaseUS backup software). I ended that process and restarted UniGetUI. Unfortunately the log error remains.

Maybe this is an elevation issue again? "you can run nancy as a user - config.urlreservations.user = username". Or perhaps this is related to using a VPN (self-host things sometimes don't work without specifically configuring / allowing them)?

Not sure what Nancy is used for but UniGetUI appears to work fine despite the error.

[marticliment]

Nancy is used for "Widgets for UniGetUI" and the "Share Packages" feature, UniGetUI should be able to work without it (in fact, it can be disabled from the settings).

If it is only localhost there should be no need to reserve the port, but perhaps EaseUS software already has this port reserved for itself

[redactedscribe]

I was looking and looking and couldn't find it. If anyone else is wondering, it's here:

"Widgets for UniGetUI" is for use with Dev Home (another software).

I will probably just disable this feature. Thanks for your help.

Edit: Disabled. No more error. Not exactly a solution, but good enough for my purposes.
