Remote DB Connection

[PoppaBuzz]

I'm not sure if it's just me, but I'm having trouble with remote database connections to my MariaDB. 
I have set my Access control to "Allow remote connections from any host."

I am able to connect to my database from my HelioHost pages, but not from my externally hosted pages. 

I can provide any necessary details upon request, just don't want to post anything too private that people could misuse.

What are you using for the hostname when connecting externally?

DB_HOST = "johnny.heliohost.org"
DB_PORT="3306"

Are you able to log in via PHPMysql? Trying to diagnose the issue by eliminating potential issues.

Yes I am.

Exact same .env file, exact same .php file. 3 different domains.

What IPs are the failed connections coming from? 

They might be blocked in our firewall.

This is the one I really care about: 104.21.50.86.
This is the one I created just for testing purposes: 185.176.43.110.
