Resolved Wordpress sometimes shows the registration page

[Epizefiri]

Server operating system version

Ubuntu 20.04

Plesk version and microupdate number

Obsidian 18.0.42

Hello,
on my plesk server I have several WordPress installations, one of them is a multisite ( let's call it "multisite.io" )
I recently installed a new WordPress website (let's call it "recently.io" ), sometimes when I visit recenlty.io I get redirected to "multisite.io/wp-signup.php?new=recenlty.io"

The page just says "Registration has been disabled."

I think that somehow the server thinks that I would like to register a new subdomain for multisite.io

How to fix?

Have the same problem. Have you resolved this?

@SLOposum
I solved using the alias functionality

So Mainsite.io is where the WordPress installation lives, while subsite1.io and subsite2.io are aliases of mainsite.io
