Server Disconnection Errror

I am trying to login to the Adobe Creative Cloud application on my PC, and regardless of how many solutions I have tried, I keep getting the Server Disconnection Error. Turning off firewall, flushing dns in CMD, resetting routers and modems, clean and repair tools, all the things they say might be the problem. I have activated a Substance 3D Educational Licence (Substance 3D for Students and Teachers), and tried login into the substance installer, still no luck. I have tried to find somewhere to get live and REAL customer support, but the AI Chatbot wont allow me to due to not having a plan? What else can I do?
