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.

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 #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.
