Which browser are you using? Is your browser stripping anything? For me this all works with demo.eduvpn.nl which is on the same server version as surf.eduvpn.nl

I use Firefox 148.0.2 (Flatpak), I cleared all cookies, cache and temporary files, but I still run into this issue. Also when I downgrade to EduVPN 4.6.0. That used to work fine. When I copy the link into Chrome it does work. So for now I can get it to work.

Then this is an issue with your firefox browser, or the flatpak specifically. In the new version we have switched from GET to POST for this callback. This improves security. Can you try a totally new firefox profile?

I found the issue, I use strict Firefox Containers for my work, to separate cookies. I had to add the localhost:port URL to that container for it work seamless again with Firefox.
