Hello,
I followed this tutorial
www.digitalocean.com/community/tutorials/how-to-upgrade-to-ubuntu-20-04-focal-fossa
and have now been shut out of my previous 18.04 ubuntu server installation.
I just would like to know where to begin to remedy this. I have no idea where to start.
If possible I would be ok with down grading from this.
the site is www.cytojer.com
I am self hosting it using WordPress.
Thank you.

Heya @jweinstein86,
The error you are getting is 502 Bad Gateway. There are a couple of possible issues starting from your WebService(Nginx) to your Application.
The first thing you need to do is check your Nginx’s error logs. You should be able to find them in /var/log/nginx/error_log. Try to open your website and check the last 50 lines.
tail -n 50 /var/log/nginx/error_log
Once you have them paste them as a comment here and I can further assist with the error.
Hey!
Happy to hear that you’ve got it all sorted out! In case that anyone comes across this in the future, here is a step-by-step guide on how to troubleshoot common Nginx problems:
Also, as a side note, I would advise on making usre that you have backups enabled before proceeding with such major upgrades:
