This is a repost, but the original thread I tacked onto isn’t showing in the support category so not sure if anyone will see it. It is here:
I had another network problem on my gateway after the update, which
was resolved by editing /etc/network/interfaces
(whonixcheck fail: tor.pid does not exist after upgrade from Whonix 11 to Whonix 12)
Everything seemed to be working for a day or two after that. Then I’m
not sure if it was after a reset or when it happened but I have lost
network connection on my Workstation. Gateway still has a connection. I
did not touch Workstation networking.
Whonixcheck on Gateway comes back all good.
Whonixcheck on workstation “ERROR: Tor Boostrap Result: Tor’s Control
Port could not be reached!”
ifconfig looks correct on both as far as I can tell, but haven’t tried anything else besides rebooting.
