A large number of redirects after migration of website. How to fix?

Migrated site on Bitriks.
The admin panel opens normally, but the site gives an error:
"The site performed the redirect too many times.

Tell me how to fix it? What to check?

Was changed web hosting, domain and PHP versions (5 of 7).
The normal hosting, not VPS.

.htaccess cleaned from unnecessary redirects, now it looks like this.

An ErrorDocument 404 /404.php

<IfModule mod_php7.c>
