Hi @SandyLightCyanSubmarine,

The error you are seeing seems to be related to your Nginx service. I’ll recommend checking ou the logs. There you can see a more detailed message rather than the generic 502/504/524 error codes. The Nginx error log can be found at /var/log/nginx/error.log. When checking it, you can see the last 100 or 200 lines to see the error

  1. tail -n 200 /var/log/nginx/error.log

There is time and date on each entry so you can see the entry when you experienced the issue.

Once you know the exact error, you can either post it here or debug further with it.

I could suggest checking your Nginx error log so that you could see the actual error rather than the generic 502/504 errors.

You can do that with the following command:

sudo tail -100 /var/log/nginx/error.log

Feel free to share the log here after removing any sensitive information from the output.

Also, I could suggest the following answer here on how to troubleshoot common Nginx problems:
