Cannot see in server

This has been an annoying and constant problem for my favorite server and it really started when the October update came out. Whenever I try to get on said server, the screen gets stuck on the “Sending Client Info” page. I can move, talk, and chat, but cannot see. When I try Alt+Tab and go back to GMOD, the screen just turns black with the same problem. This has not happened to any other servers except one and the server went to Dual-Hosted servers shortly after the update. About a few days after this, I couldn’t connect. It only happens to their On-Ship server and not their Event server. The Event server is just fine for me. Please help me. I would like to get back onto my favorite server.
