I am using a fresh install of ubuntu 20.04.
I just ran the installation script as instructed on the main page. When everything is done, it asks to reboot, and I let it.
After the reboot, I try to visit the control panel, and only get an error. If i try the machine’s IP address, I get a nginx 502 Bad Gateway error. If I try the domain name, I get an apache error 500.
An example line from the nginx error log says:
2021/01/07 12:09:24 [error] 1392#1392: *146 connect() failed (111: Connection refused) while connecting to upstream, client: IP_of_a_computer_on_LAN, server: mydomain, request: “GET / HTTP/1.1”, upstream: “IP_of_the_server:8080/”, host: “mydomain”
