SSH remote debug error "Broken transport; encountered EOF"

Hi JetBrains Team,

I am using a GPU cloud environment and connecting via SSH for my work. Previously, I was able to run AI model training and debugging without any issues through the run configuration settings.

However, after a popup related to memory heap appeared and I clicked on it, something automatically ran and the IDE restarted. Since then, I have been able to run my configurations, but debugging no longer works.

When attempting to debug, the message "uploading PyCharm helpers" appears, followed by "Broken transport; encountered EOF" in the debug console, with no other logs.

Checking the SSHD log on the remote server, I found the following entries:

debug2: load_server_config: filename /etc/ssh/sshd_config
debug2: load_server_config: done config len = 3255
debug2: parse_server_config_depth: config /etc/ssh/sshd_config len 3255
debug2: /etc/ssh/sshd_config line 12: new include /etc/ssh/sshd_config.d/*.conf
debug2: /etc/ssh/sshd_config line 12: no match for /etc/ssh/sshd_config.d/*.conf
debug1: sshd version OpenSSH_8.9, OpenSSL 3.0.2 15 Mar 2022
debug1: Unable to load host key: /etc/ssh/ssh_host_rsa_key
debug1: Unable to load host key: /etc/ssh/ssh_host_ecdsa_key
debug1: Unable to load host key: /etc/ssh/ssh_host_ed25519_key
sshd: no hostkeys available -- exiting.

Despite SSH connections and running configurations working fine, debugging fails with the same settings. I have tried deleting the .pycharm_helpers folder on the remote, invalidating caches, deleting and re-adding the SSH connection, and reinstalling the cloud session, but the issue persists.

Could you please assist in resolving this?

Thank you.
