Hello everyone, I introduce myself, my name is Alexander and I am a new user, I know very little nginx, can you give me a hand? I set up a reverse proxy ssl, but when I try not to use ssl by changing the configuration file according to some still are not able to go to the server. Can you help me edit the configuration file? Thank you :)
