I did a clean install on a DigitalOcean Droplet - Ubuntu 22.04 with SSL. After going through the install (using reconfigure option), I get a Service Unavailable message when visiting my endpoint.

Following this forum thread: https://community.openproject.org/topics/7681, I ran:
 "sudo openproject run web"

and also tried:

sudo service apache2 start

sudo openproject run web

Also, following this thread: https://community.openproject.org/topics/14900?forum_id=9, I made sure to run "sudo openproject configure".

Also when running 

curl -I localhost:6000, I get the following error:

curl: (7) Failed to connect to localhost port 6000 after 0 ms: Connection refused

Other things I ran/tried:

sudo systemctl status apache2 - shows apache is Active (running)

sudo systemctl status openproject - shows openproject Active (running)

I'm not sure how to proceed. Any help on how to continue to debug/fix this install would be greatly appreciated!

Here's the errors I'm seeing:
