How to access Camunda Cloud from inside corporate network

Camunda 8 Topics Discussion & Questions
1

Hi

I’m building a PoC

I was able to run from my local pc the Java client at GitHub - camunda/camunda-platform-get-started: Camunda Platform 8 - Get Started Projects.

Now, when I try to run it from my corporate PC, I’m getting the error below. I understand that I need to fix some network configuration to make it work. Is this configuration documented anywhere? Many thanks.

Best regards.

I’d recommend discussing this with your corporate PC administrator. Perhaps it blocks one of the connection specified in the configurations. See zeebe/broker.standalone.yaml.template at develop · camunda-cloud/zeebe · GitHub for a complete overview of Zeebe Broker and (embedded) Gateway configurations.

Hope it helps.

Try using zbctl and see if you can get the cluster topology with zbctl status. This is the most basic gRPC API call and the best one to see if the communications are working.
