I am busy doing an upgrade on VMware Site Recovery Manager from version 8.1.2 to 8.3.1. The upgrade went successful but i am not able to pair SRM servers on both protected site and recovery site.

vCenter server version is 7.0U3.

SRM services are running.

Below is the error i am getting;

Unable to retrieve Site Recovery Manager summary data.
Unable to connect to Lookup Service at https://vwt-single-sign.mascom.bw:443/lookupservice/sdk. Reason: https://vwt-single-sign.mascom.bw:443/lookupservice/sdk invocation failed with "java.net.ConnectException: Connection timed out: no further information"
