Ubuntu Zcash Mining Pool Setup Troubleshooting

I need assistance troubleshooting a Zcash mining pool installation on Linux. The specific issue I'm facing is that I encounter a 502 error when accessing the panel instead of seeing the expected interface. This seems related to configuration file settings.

Your expertise in diagnosing and resolving configuration issues within Linux environments is essential. The goal is to fix this error so the mining pool operates correctly. If you have experience with this type of setup, please get in touch!
