We do have a Policy Action to switch client to use Automatic Relays, We have 3 regions ADC, EDC & PDC, and as per relay affiliation seeklist server should connect to one of the relay from this seeklist, which it does for some time say 1 or 2 hour.
And we are facing this issue only for couple of subnet on cloud machines. Can it be something related to Firewall ? I am just assuming/guessing.
I have gone through the logs as well and I am not able to find anything in that. when it Begin Relay Select - it communicate with relay to its specific region and after wards say like 1 or 2 hours it will try to register to the Root server as a relay and there I get below mentioned error.
