Error my redirect to my main

i have 2 domains, suddenly my second domain2 redirect to my first main domain1, only on Firefox on desktop, on Chrome desktop it’s good but on my Chrome Android phone same error, even when my domain2 has no database and no script it all (empty domain) i have cleared cookies and cache, how to fix this?

when i add this ?random_string after my domain URL like it’s working, so is this problem from my browser or server side, plus as i said, also on my chrome android phone has the same issue

I’m having a very similar issue. My sites show properly with ssl but without it they all redirect to the default domain.
