Website built on Wodpress works fine on all browsers but /wp-admin for some reason redirects to [ip.address.here]/wp-admin only on Chromium based browsers - Chrome, Edge and Opera giving Nginx 404 not found error. That IP address is not even the site's own IP address.

Wp-admin works perfectly on Firefox and Webkit browsers.

I have purged all caches, from WP to DNS, tried to change 3rd party cookie rules and even deleted all cached website data from browser, nothing seems to work.

I have also updated WP and all plugins to all the latest versions.

Also all URLs in settings refers to domain, not IP address.

What could be the problem?

Update: On further investigation, when going to [domain]/wp-config, it first results to 301 (from disk cache) and then redirects to the IP address one.

please delete the cache from your cache... and, also delete the cache from your browser

Might be some plugin or theme conflict. Can you check once by disabling the plugins and switching back to the default theme if that makes some change?
