Hi! 502 Bad Gateway is actually a good sign regarding your nginx conf, your original nginx conf with 127.0.0.1:4036 looks correct to me. It seems that the ditto process is unable to start - could you cd to /opt/ditto and then run ditto there directly with `deno task start` and let me know what happens? 

Also, if you wouldn't mind we can get on a Jitsi Meet or something at some point to figure this out, it would be much faster. Please let me know your availability (you can email me at me@shantaram.xyz) if that is acceptable. 

 Thank you. I’ll reach out to you soon.
