(I got this problem 5 days ago more or less)
I am on a restricted wi-fi network so the only surfshark protocol that works for me is openvpn udp, it works on windows 11 for me and when I first installed surfshark in discovery from flathub it worked up until yesterday, but today for some cosmic unknown reason it decided to tell Error occured request timed out Cause:unset, when connecting to fastest server when connecting to a specific city it said the same thing but slightly different, timeout Cause:unset.
I am now using it and found that the only connection that works is the one I connected to previously with my phone’s hotspot, so if I try now to connect to any other city is gives me the same problem as before, but I can connect to the city to which I connected to earlier with my hotspot. I doubt this is a problem of the surfshark app since it works fine on windows 11, I am now on fedora 44 kde plasma, fresh installation and I have the same issue, but to be safe I also contacted surfshark suppport and after 1 hour of changing settings trying a manual vpn through the konsole it still wouldn’t work.
