Wordpress multisite subsites pages permalinks

Hello, I have a working wordpress multisite installation with subsites using subdomains.

Everything was working fine with pages under subsites working with the %postname%/ setting in the permalink options, but suddenly permalinks of pages inside subsites (mainsite.com) stopped working, only plain permalinks works.

Subdomains and http to https redirection is working fine, but subsites inner pages are not.

Any idea on what is not working here? thanks in advance for any help you can provide me.

This is my htaccess:

Rewrite Rules Added by CyberPanel Rewrite Rule Generator

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]

End CyberPanel Generated Rules.

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

add a trailing slash to /wp-admin

RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^/ - [L]
RewriteRule ^/(wp-(content|admin|includes).) $1 [L]
RewriteRule ^/(.
\.php)$ $1 [L]
RewriteRule . index.php [L]

Solved myself, for an unknow reason the rewrite option on OLS was off for the domain. Activated to read from .htaccess and everything was working again.
