Hello guys,

When I try to update my system with discover or the terminal I got an error saying update not possible since 2 weeks now.
Here is my specs :

KDE Plasma Version: 5.27.3
KDE Frameworks Version: 5.104.0
Qt Version: 5.15.8
Kernel Version: 5.19.0-38-generic (64-bit)
Graphics Platform: X11
Processors: 8x 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz
Memory: 7.6 GiB of RAM
Graphics Processor: Mesa Intel® Xe Graphics
Manufacturer: Acer
Product Name: Swift SF314-510G
System Version: 1.03

And here is the error I am facing when opening discover, I think my KDE neon repos can't be reached anymore and I don't see them in discover settings either :

How can I add them back ? thank you for your help

PS : Muon package installer was able to update my system so it seems the issue is coming from Discover.

Using Muon also reinstated my packages into discover settings but I still got this error when refreshing the update page:

*All* of your repos are marked with this local IP address, which seems to indicate a networking/proxy or similar issue.

Thank you for your help claydoh. Indeed I did add this proxy IP 2 weeks ago to make a test but then I disabled the proxy and even reset this manual configuration from settings. It seems discover app kept this proxy for some reason... Do you know how I can fix this ? thank you !
