Can't connect to my friends server

Cheers guys,

following problem appears today:

Just logged in as normaly to teamspeak, after a good hour a disconnected the server for around two hours. After this break i want to logged in, but nothing worked. All of my friends could connect to the server

Following steps i did already:

  • Restart PC
  • Restart Router
  • Changed DNS-Server
  • Looked for updates and reinstalled teamspeak
  • Did a clean installation, without anything data left
  • turned off firewall
  • tried with my phone (mobile data worked / with wlan doesn’t worked)
  • checked my router configuration
  • i can connect to voice.teamspeak.com
  • ping doesn’t worked a while ago, now it worked fine

so nothing really helped me… it just appears randomly, no update, no change

The interesting part was… it coulnd’t connect to myteamspeak.com / community.teamspeak.com / etc.
other websites worked very well. At the moment the websites are working… but still the connection to my friends server does not work and i also can’t find any server in the all server list

logs, when i try to connect:
