Kaczorek,
I ve cleared my browser cache and cookies. Unfortunately that didnt fix the issue.
I still get the failed to "connect to server " banner . I can connect to astroberry.local (and astroberry.local ), I can ssh to the server as user astroberry,
I can ping my remote pc, google.com, from the server (as user astroberry), and I can also ping (from my remote PC) astroberry.local.
Connectivity seems fine.
I guess I ll just start over, re image my SD card with raspian buster, follow the installation instructions a second time and see what happens.
Thanks for your help, it IS greatly appreciated!
