Screen stuck on "Connecting to reMarkable..." but red-dot is there, seems to be stuck on authentication

[wulfdewolf]

I have a RM2, I've set backend to "screenshare". When I connect rmview seems to be stuck on the connecting screen, although when I move my pencil across the screen the red-dot updates live.

I tried and succeeded to use rmview at home. On 'eduroam' at university I can not seem to connect though.

Verbose output:

Can you check if #146 helps (especially the newer comments)?

[wulfdewolf]

I had already implemented that fix when I experienced the same issues as #146 . The issue must be related to something else.

[bordaigorl]

Sorry for getting back so late. Given rmview seems to work on some networks and not others this suggests it is a network configuration problem (see #111). I would not expect eduroam to let you use the necessary ports for authentication. I would suggest connecting to the tablet using a USB cable.

Hi, just chiming in with the same issue here using Version 3.9.3.1986. The ports are wide open, and it doesn't quite seem to be the same issue as https://github.com/bordaigorl/rmview/issues/146 but seems very similar in that it hangs when it's trying to get the config file from the rm.

I'm on 3.10.2.2063 facing the same issue: can see the red dot while hovering the pen but can't actually see the screen, not on USB, not on Wi-Fi either.

Same issue as viktordimov on 3.10.2.2063

~I get the same error, I'm stuck on the connection screen but my pointer is working.~

~As far as I can tell, /etc/version contains the correct value.~

~I'm using rmview from nix, version 3.1.3.~
