Cant access Directadmin on any of my 4 VPS systems

Hi.

All of a sudden i cant access Directadmin on any of my 4 VPS systems. The page shows (freely translated from Swedish) "Error when getting the page. Connection closed, Server on xxx.xxx.xxx.xxx did not answer"

When i run netstat -pantu | grep 2222

I get:
tcp6 0 0 :::2222 :::* LISTEN 745/directadmin

All worked fine yesterday.

What can be the cause to the error?

Best regards
Jukka

Edit: So bonkers.. I set my home router firewall setting to tight and that lead to not be able to connect to my servers. Changed back and all good again.
