Issue
I need help securing my n8n server on domain.com:5678 with SSL. HTTP functions correctly while HTTPS fails. I use Let’s Encrypt, Docker, and CyberPanel on CentOS 7.
I encountered a similar situation recently and found that the root of the problem was the way the SSL certificate was integrated within Docker. I had to ensure that the certificates from Let’s Encrypt are correctly mounted and that the container is configured to accept traffic on the SSL port. In my case, adjusting the reverse proxy settings in the container made all the difference. Reviewing and updating the paths to the full chain certificate in the configuration file also resolved the handshake issues.
Experience has taught me that the key to addressing this issue lies in ensuring that SSL certificates are properly integrated into the Docker container while making sure all port mappings and file paths are correctly configured. I observed that even minor discrepancies in the certificate file paths can disrupt the SSL handshake. Moreover, it is important to confirm that the container is rebuilt after updating certificates, particularly with CyberPanel involved, as it might impede new configuration settings from being correctly applied on port 5678.
i had a similar issue. the key was making sure docker was mounting the right lets encript cert files. i changed the config and updated the proxy settings and that fixed it. hope it helps!
In my experience, the challenge often lies in ensuring that the Docker container correctly receives the updated SSL certificate files. I once faced a similar issue and realized that the directory where the certificates resided wasn’t properly synchronized with the container’s internal directory. Rechecking permissions and making sure reusable volumes for certs were established helped resolve the problem. It is also good practice to review both CyberPanel and Docker’s network settings to eliminate any potential conflicts or misconfigurations.
Based on my own experience working with Docker and Let’s Encrypt in similar setups, I determined that even though HTTPS failure is often due to misconfiguration, it sometimes results from conflicting internal mappings within the container configuration. Careful attention to the certificate renewal process is crucial, ensuring that any updates propagate correctly in mount points. Additionally, testing connectivity from within the container itself helped isolate the error. Finally, verifying that the CyberPanel configuration recognized the new SSL files proved to be an indispensable troubleshooting step.
