Antivirus client update inconsistency

[solas 0]

I am still battling with client update inconsistency.  Sometimes they fail and then I try again a few minutes later and they are successful without any changes being made.  Agent trace logs are showing the messages below  and the ESMC console shows Failed to synchronize package repository. See trace message for more details.  The name of the server resolves accurately on the client and I have windows firewall rules to allow the ESMC server on all ports.

Hello @solas,

Do you refer to "updates" (module updates of products) or to "upgrades" (installation of a new version of agent / endpoint).  As package repository is needed only for the second one. 

Thanks,

Michal

In this case I am trying to install a new version of the agent.

The error you have passed is not from the failure of the particular component upgrade task, rather from the failed replication attempts. How is your repository configured in both agent policy and server settings? Did you configure it for autoselect, or you specified a specific repository address ?

As already mentioned, there are multiple critical/fatal errors in trace log you provided. For example:

Error: CNetworkGrpcModule [Thread 31a0]: GRPC:Failed to resolve: <esmccompanyhostname>.com:2222

indicates that it is not possible to resolve DNS name of where ESMC is supposed to be running.

The repository is set for autoselect

While the log says that it cannot be resolved, I am able to nslookup the hostname of the server from the client and it responds correctly.  I can also nslookup the name of the client from the ESMC and it responds correctly.  I have firewall rules to allow the ip of the ESMC inbound on all ports.  The client is currently reporting in tot he ESMC just fine and has the most up to date version of the agent.  I am just unable to install the latest AV client.
