When I try to join multiplayer servers, it just says they are 'Pinging' and after a couple of seconds they say 'Cannot connect to server' and when I try to join the server, it says 'Logging in..' and then says 'Disconnected' a few seconds later. This happened yesterday too, and that was the first time it happened. 3 whole hours later, and it worked. This is the second time and I've been waiting 2 hours, with nothing. I've done all the basic stuff, re-installed minecraft, disconnected internet and reconnected, unblocked firewall,etc. My internet itself works fine, I can surf the web with no problem. Looking around for solutions, someone had said to type in the Command Prompt 'ping server IP', so I typed into the Command Prompt 'ping server IP' and it says:
"Pinging IP [xxx.x.xxx.169] with 32 bytes of data:
Reply from xxx.x.xxx.169: bytes=32 time=311ms TTL=236
Reply from xxx.x.xxx.169: bytes=32 time=294ms TTL=236
Reply from xxx.x.xxx.169: bytes=32 time=327ms TTL=236
Reply from xxx.x.xxx.169: bytes=32 time=317ms TTL=236

Ping statistics for xxx.x.xxx.169:
Packets: Sent = 4, Recieved = 4, Lost = 0 <0% loss>,
Approximate round trip times in milli-seconds:
Minimum = 249ms, Maximum = 327ms, Average = 312ms"
I hid the IP for privacy reasons but if needed I can uncover the IP.
UPDATE: It's been 5 hours now, I went off my PC for about 2 hours and it still doesnt work..?
