Hi Evren, I'm not sure if --pry plays a significant role here. The DISPLAY variable, by default, is set to localhost:port_offset. SLURM itself doesn't do any x11 forwarding so when your remote application attempts to connect to the x11 server on the submission node, unless they're the same, the connection will fail. The solution is to set X11UseLocalhost to no in your sshd_config's on your clusters nodes, restart sshd and login again.
