Issues Connecting IntelliJ IDEA to Enterprise Server for Remote Development

Hi everyone,

I'm reaching out because I'm running into some issues while trying to connect IntelliJ IDEA to our enterprise server for remote development. Our setup involves using a self-hosted Git server and a few different CI/CD pipelines that all run on a shared enterprise server. We’re trying to use IntelliJ IDEA’s remote development features to streamline our workflow, but unfortunately, I’ve been running into some connectivity problems.

Steps I’ve Taken:

• Configured the remote development environment: I’ve made sure that the server is accessible via SSH and that all firewall settings are configured properly on the enterprise server.
• Verified connection settings: I’ve double-checked the remote repository URLs and SSH keys used for authentication. They seem fine since I can access them without issues using the terminal.
• IntelliJ Remote Development Settings: I’ve gone through the "Remote Repositories" configuration in IntelliJ, and everything seems correct there, too.

The Issue:

When I try to clone a repository from the enterprise server or attempt to use IntelliJ’s remote tools to access files, I get timeouts or connection errors. Sometimes, the IDE fails to authenticate even though the SSH keys are confirmed to be working. The most recent error message I received was:

"Unable to establish a connection to the remote host: Timeout while waiting for a response."

Things I’ve Tried:

1. SSH Configuration: Verified the remote server's SSH configuration, and the server logs show no failed attempts or issues with the SSH service.
2. Network Configuration: I also tried adjusting my proxy settings and disabling any VPN connections to ensure no interference with the connection to the enterprise server.
3. IDE Version: I’m using the latest stable version of IntelliJ IDEA (version 2024.x), but I’ve also tried rolling back to an earlier version in case the latest release had a bug, but the issue persists.

I would really appreciate any guidance on how to resolve this. Has anyone encountered a similar issue with connecting IntelliJ IDEA to an enterprise server for remote development? Any troubleshooting steps or settings adjustments that I might have missed?

Thanks in advance for any help!
