Problem with connection. "Failed to connect to server/SRV DNS resolve unsuccessful"

Hey there. Yesterday everything was working just fine. Today I try to connect and I can't. I get "Failed to connect". Tried to connect via IP but still same issue. What is strange I can connect to other servers (voice.teamspeak), can ping it. My friends aren't experiencing any issues with our server, except me. Here's the log:
