Hi,
I am using pverser on a HPC environment. when I connect to the server from a ui client I get the error.
display not accessible on the server side.
As far as I’ve read, it is because the x server is not running on the server nodes. However, I checked the nodes configuration and the xservers are runnig.
This is the error log in case it help.
