I have a problem when making a new server. I get the error 'we were unable to connect to the main Socket.IO'.
I followed the steps of this post https://community.pufferpanel.com/topic/146/socket-io-ssl-problem
I followed the steps of this post but no result i openend the ports as well.
I do not use ssl.
node is on the same vps.
i do not use docker.
Have you tried clicking the error message and accepting the certificate?
