rmview does not proceed with authentification

[LabChameleon]

I have installed rmview via pip on ubuntu and I am using the remarkable patch 2.10. I have established a ssh key with the tablet
and I am able to connect to my tablet via ssh connection. However when using rmview its does not proceed with the authentification.
I get the following log and then nothing is happening anymore:

my config file is the following:

  1 {

I have the screenshare feature activated on my tablet. Any insights what might be the problem?

It looks like the ssh connection works, but the authentication with the tablet hangs.
It could be that the ports involved in the auth are not open?
Have a look here #111 to see if that helps.

yes, apparently the problem seems to be similar. If I allow all incoming connections in my firewall the authentification works fine. I will however look for a better solution than just allowing all incoming connections.
That already helps a lot, thank you!
