Unable to establish communication with server callback channel (Version 7.1.1)

[thomasevers]

Hey all,

I get the following message when trying to start a process:

"Unable to establish communication with server callback channel. This will prevent certain features from functioning properly. If this error persists, please consult the documentation: https://bpdocs.blueprism.com/bp-7-1/en-us/ascr/ascr.htm"

Does anyone know what could cause this to happen?
Using version 7.1.1 Application Server + Authentication Server.
Tried opening the port 10000 IN and OUT on the RR (VM), but still the same.

I do want to add, that it's possible to start a process, but this window pops up every time.

Thanks for your help in advance!

Following, I get same issue - doesnt stop me actually running processes but it is an annoyance. Have also tried opening ports.

@thomasevers @james.keefe  If you haven't already, try the steps this support article suggests: https://support.blueprism.com/en/support/solutions/articles/7000076986-bpe-error-unable-to-establish-communication-with-server-callback-channel-when-trying-to-run-a-proc

I have tried to follow the steps in the article without any luck. 

We also did a port scan, and it seems that port 10000 isn't open on the App Server, even though we have disabled firewall.

Should I try another port?

Thank you for your help in advance

If I were you, I'd engage with Blue Prism Support and make them figure it out hahaha
