BP v7.0.1 upgrade and callback channel error

[HongJooChoi]

Hi, Community.

Can anyone guide us regarding the following error message?

We have upgraded the BP from 6.8.1 to 7.0.1 and ASCR setting remained as default with its port = 10000, hostname = localhost, callback = gRPC.

We changed the port number to 20000 for try and fortunately, the server started successfully at the moment.


Since then, we have tested the RR by drag-n-drop the process from the control room, when we came across the following error:


Would there be any way to troubleshoot this?


Best regards

Hello,

We have a Knowledge Base article that describes this error with some troubleshooting steps to try; "Why do I get error message "Unable to establish communication with server callback channel." when trying to run a process after upgrading to Blue Prism 7?"

Have you reviewed this and implemented the suggestions? If so, what were the results?

Hope this helps.
