what I have configured is the following:

cluster is 9.1 LTS ML and my python version is 3.8.10 in the base conda environment

I did had the server enabled but did not set the port to 8787 in the cluster settings.

I tried setting the port of the cluster to 8787 while keeping the server enabled but it was no good. Still got the same error.

I do not know if I have a 7 layer firewall. Is there a way to see it?
