Unable to connect to a specific server.

Hello since about a week ago I've not been able to connect to a specific teamspeak server it's IP is 176.57.131.174:3185.
I am an admin on the server, so I'm sure I'm not banned, there is no password and the IP is definitely correct. When I ping the IP(without the port)
I get a response, but whenever I try to connect via teamspeak client I get this.

As you can see this is not very helpful. My firewall allows TS access, and I'm tried all the common things, rebooting my PC, reinstalling TS3, rebooting my
router and turning off my firewall. Only the last thing did anything, after I completely turned off my firewall on the third try at connecting to the server
I finally did connect, however I was then disconnected after 25 seconds and couldn't connect again. Another admin checked the server logs, and it said I
lost connection, so I assume this is an issue on my end.

I can connect to all other TS3 servers fine however, so I'm rather confused. I'd appreciate any help you could offer.
