Completely agree with you, creating and configuring a server is not an easy job if you want it to be of high quality and work without failures. I recently created my first server, some of my visitors, mostly friends, faced the error OpenGL 1285, I found a solution on this site, it turned out many have not updated the launcher Optifine to the latest version, of course there are other reasons for this error, but many helped by simply updating to the latest version. Live and learn.
