Can't install Wordpress - "The site is experiencing technical difficulties."

[bgbs]

"The site is experiencing technical difficulties."
Usually this error message is associated with some plugin issue, but in my case this is a totally fresh Wordpress installation, and I'm getting this error during installation.
I'm running latest Ubuntu 18.1 and php 7.2 on Digital Ocean cloud vps service.
I'm not sure if this error is related to Vesta or the VPS.

Let me know

First thing,
Use mxtoolbox.com and check your dns is resolving for your domain.

You can also check subdomains...ie hostname.domain.com (ie server1.your domain.com)

If that is resolving,

Check your vestacp logs...almost always the logs will either provide the answer or at least hint at likely culprits.
