Help can not access the vestacp panel I get error "504 Gateway Time-out" *_* Solved *_*

Help can not access the vestacp panel I get error "504 Gateway Time-out"

The error occurs after changing the IP of the server.

Automating IP exchange or Public DNS exchange.

I believe this error is generated "504 Gateway Time-out"

Most do not know what I have to reconfigure any server.

What files can not be modified to change IP and DNS?

What should I do?

We think this file /etc/sudoers.d/admin don't have code:

Code: Select all

# Created by vesta installer
Defaults env_keep="VESTA"
Defaults:admin !syslog
Defaults:admin !requiretty
Defaults:root !requiretty

If you paste this, all will work (as we hope)

Don't forget restart vesta service.

I have a similar problem. All the websites hosted on the server work fine, but the vestacp panel always shows a 504 error. This problem begun only a few days ago: Everything was working perfectly till then.
