LSF cluster cannot connect to instance from local computer

[trieudnguyen]

Hello,
I am trying to connect to an mapdl instance started on an LSF cluster.
I have the instance started successfully in GRPC mode and the ip port are indicated in the picture below:

when trying to connect on the local computer I am getting this error:

Any help would be greatly appreciated.

Thanks in advance

SOLVED:

I needed to create an SSH tunnel on cluster side to the host node that was running the grpc instance because it was behind a firewall. Then I had to create a tunnel on my local machine to the host node.

Hi German, I posted another discussion around an open_gui crash. Was wondering if you have any ideas what the issues might be? Thanks Trieu
