These errors are very weird to me, seems like a redirecting issue somehow triggering SSL?

Which browser are you using? Either chrome or firefox should work. Try with those first with a clean profile (no extensions)

Otherwise try the following in order:

• Try connecting to the Radboud using secure internet and let me know if that works
• Delete the local configs ~/.config/eduvpn and try again
• Try if another client works (window, android, iOS, macOS) to rule out a network error
• Do you have some kind of firewall that might be an issue, either on the network or the linux install? Try another network if possible

[paulzerr]

I'm connecting via Eduroam wifi (university network). My colleagues are using the same (on windows) and it's working fine. I don't have another linux user nearby to test this with.

There is no eduvpn in my ~/.config (the gui is working though).

There is no firewall (ufw status is 'inactive').

[paulzerr]

I have also tried connecting to a different network and different (clean) browsers. No success.

[jwijenbergh]

Sorry for the trouble but do you have the ability to try this in a VM (non kubuntu)? Also tried re-installing the client?

In the meantime let me set up a kubuntu vm

[gijzelaerr]

i'm also quite puzzled by this error log. This doesn't seem to come from eduvpn logging? Or is the webserver we run not using the python logging?

In your browser, when you do the oauth redirect. What does it say in the url bar? Does it maybe say https 127.0.0.1?

I mean when you reach this page

[paulzerr]

The url bar says

[paulzerr]

I'm bad with VM's, but have tried reinstalling the client.

[gijzelaerr]

it really looks like your browser is insisting on sending encrypted (HTTPS) traffic to a non-encrypted port (HTTP). What browsers did you try?

[paulzerr]

Clean chrome, firefox

[gijzelaerr]

could it be that ru.eduvpn.nl forces the session to continue in https? No idea how that would work. also, the windows client doesn't seem to be bothered by this.

This is all super strange.

[paulzerr]

could not resolve the issue, can't access university IT stuff I need for work, am sad

are there any problem solving approaches you would recommend?

[gijzelaerr]

Sorry we can help you, but this is quite a rare problem. Try to isolate the issue, this is somehow specific to your system and configuration. You could try to see if you can get it to work on a new user account on your computer. Otherwise a fresh install of your OS ( on a different machine first).
