I have this problem that is super annoying which always say Failed to connect to server. I turned off my Anti-Virus, Firewall, added TCP and UCP to Windows Firewall, I changed my network type to Home, I changed my DNS to, I changed my secondary DNS to and I also pinged the server.

Any solutions? I have surfed the web and found no solutions at all that work.

Note: Don't keep saying that re-installing the operating system will fix the bug.
Note 2 : I have checked my internet stuff, its all fine and alright.
Note 3 : My identity security level is 25.
Note 4 : This problem is happening on all of the Teamspeak 3 servers.
Note 5 : I tried connecting to Hypixel, Mineplex and Badlion Teamspeak 3 server and my Teamspeak is up-to-date and their server has people and it is working 100%

Device : Laptop.
Brand : Hewlett Packard [HP].
Operating System : Windows 7 Ultimate 64 Bit.
Anti-Virus : Eset Nod32 Anti-Virus 9.0.381.0.
Firewall : FortKnox Personal Firewall 8.0.705.0.

Thanks for taking your time to read this and help me please.
