Server connection issues

Hi there. Sometimes the server will let me in, sometimes it won’t. I know it is up because there are other people in there. This is the log, minus server IP:

10/28/2020 23:18:05 ClientUI Info Failed to connect to server, want autoreconnect = 0

Originally I had teamspeak port forwarded. I removed the port forward last night, and it let me connect. Now this evening, I cannot connect again. I am on version 3.5.3 on Windows 10
