Use an NTP on the VCS and on the Endpoint.

If you think you are using one, check the status of the NTP and that there is no firewall blocking someting.

Sir We dont have NTP server in our office. but will it really affect by using NTP ? because we are able to dial on different Public IP except this perticular Single Public IP(115.111.249.140). In Client side they are also uses VCS. and same error occured from their end. followings are error logs.
