Client is not authorized to connect to Server? JS8

[Julian White]

I have this second Pi Zero2W on my network and cant get JS8 to run. Here's what the log show's. It keep retrying and failing.

I'm not sure if the IPv6 warning is related. I don't see that warning on the other pi on my network.

I was able to recreate this issue by just changing the hostname.
I have no idea how to fix this though, other than just leaving it default?

Great detective work!  I was about to ask if you changed the hostname.

The problem is with the /home/pi/.Xauthority file being read-only on DigiPi.  The workaround
is to start js8call after pressing [save configuration].  This is only a problem if you change
the hostname (in /etc/hosts and /etc/hostname).

This makes the filesystem read-write, js8call caches credentials with the new hostname
in the .Xauthority file, and it will work forever onward...

cool,

Turned out to be a easy fix. All I needed to do was follow the instructions completely.

"and also add your hostname to the list next to 127.0.1.1 in /etc/hosts" - turns out to be pretty important.

Thanks for the quick response!
