  • Great firewall of China perhaps?



  • I am from Europe, i don't know why my home's IP is from CN - crazy, but for all users its the same logs, also for my friend.



  • To my knowledge there is nothing you can do.
    normally it would still work if the mtu is set to automatic in the adapter settings (standard) unless the ISP is blocking ICMP traffic which is needed to automatically adjust the MTU value. (often done to prevent ddos attacks)
    So you'd have to ask your ISP for a solution.
