I know I read this on the forum somewhere last week and now I cannot find it in the searches.
I want to set UFW firewall on Ubuntu to active, but I need to know which ports need to be open first. When I set it to active without doing any “allow” settings ERPNExt stopped working and port 22 went closed so I could not even SSH into it. I had to relaod the OS and start over.
So now I know to set port2 22, 80, and I think 443. But I seem to remember there are about 2 more required ports ofr ERPNext to run.
Can anyone point me to the post that had that info?
