I got this error in the upgrade when using the BrokerGateway.

error|Prerequisite VerifyNatsCluster.dll failed: Unable to create connection with endpoints nats://10.120.7.10:4222

Migrating back to the old NATs resolved the issue

Hi,

Does the IP 10.120.7.10 belong to an agent in the cluster?
If so, it would mean that there is an issue with the nats-server instance running on that agent or that the firewall prevents communication via port 4222.

Can you verify if this is the case?
Kind regards,
Pieter Lust

It is one of the DMA's yes, but it looks like the old dll in the upgrade package, as I saw the same issue when the BPA on the system didn't update on our prod system, and all the test failed.
The cluster is talking fine on NATs though, using both new and old methods.
