In China, Sync wallet need vpn app and seting IKEv2 mode. good luck!
在中国，同步钱包需要使用VNP软件且把连接模式设置成IKEv2模式。我使用的是天行VNP，连接美国服务器。
Thank you, bro. It really works!!!
Hope dev can develop the wallet and help sync even without special vpn.
The price drops a lot yesterday. And I bought some as my wallet can sync. Good luck to XSPEC.
