I create my Wordpress site before for scratch. And a few weeks ago. I put some DNS in my ethernet section. There is no problem with that or i need to change what DNS I put ? I put only 1.1.1.1 and 1.0.0.1 for internet download speed purpose.

And yesterday I see my Wordpress site exprncing 502 nginx error. Although my Wordpress version was old. I update it and all plugins. But instead I resolve my problem it's goes to Maintenance.
