The last step doesn't work on MightySites.

Hello everyone
After a total of 21 hours and 2 IBOS tablets, I still haven't completely got it working. And I've been desperate for the last 18 hours.
1 PHP 8.4
2 Both Joomla 5.4.3
3 Main domain and one subdomain
4 Hosting provider is afahosting.de
5 MySQL 8.0
6 phpMyAdmin version: 8.0.28
7 Both Joomla installations have MightySites installed
I simply want members to be logged in and simultaneously logged in on the subpage. (Which I've managed to do, but only if the member has the same login credentials on both sites.) In other words, I have to manually enter the member's information in the Joomla backend on the subpage. Since I can't get it to work, if a new member registers on the main site and then logs in, they aren't logged in on the subpage unless I do it manually.
I could write a book about everything I've tried and how.

Subpages of both domains in MightySites. Unfortunately, only the main page works; the subpage returns an error message for some reason. ) shop.mein-treff.de: Access denied for user 'p7e3j6td_shopmeintreff'@'localhost' (with password: YES)) I can't change localhost in the IP address.
Table prefixes are different for both. Database tables in MightySites are #__session, #__user_usergroup_map, #__usergroups, #__users. The PHP configuration is set to cookie_domain.
My last question, and no one has been able to answer it, is it even possible for MightySites to work completely with the above settings?
After 21 hours, I was told that my hosting provider's security department is blocking the registration and that the browser is blocking it because of cookies, as modern browsers are stricter. Or perhaps PHP 8.4 isn't compatible with MightySites.
You're basically my last hope before I give up.
