Report BTSync blocked in China? in Sync General Discussion Posted September 12, 2014 @RomanZ the following is my nslookup result: Non-authoritative answer:Name: config.usyncapp.comAddresses: 18.104.22.168 22.214.171.124 126.96.36.199 This result appears to be correct, however, 1.3.109 still does not work on my windows 7. BTW, I can use IE to download the file from http://config.usyncapp.com/sync.conf on my disk(This indicates that this link is not blocked by GFW.)；In addition, I did icmp ping and tcp ping test for config.usyncapp.com, the result is ok. I really do not understand where is blocked, leading to not communicate in 1.3.109.
