I managed to find the provider thanks to you guys.
I already contacted them and they are going to take care of this issue.
Thank you all so much.

And what about my access to wp-admin?
I changed the wordpress url to https://and-pt.org/wp-admins along with the site url following plugin’s instructions. The previous url was https://and-pt.org/wp-admin
Which means that after disabling all the plugins I may still not have access to wp-admin.
How can I solve this problem? Is there a way to reset current user and password or to revert current wordpress url to previous url?
Or by accessing the database and disabling all plugins I may also have access to wp-admin?
Basically it would be the best solution because I have a full backup of the site and Db and it would be much easier if I could go back to the previous wordpress url to see the login page (which I don’t see now)

Finding the hosting provider is already helpful.
I’m going to contact them and see if they can help.
Hope they can.~
Worst case scenario is building a website from scratch.
Many thanks

I didn’t forget my login credentials to the hosting provider I just don’t have them and I don’t know who they are. That’s the real problem.
It seems to me to be more easier to have a new access to wp admin dashboard meaning WordPress resetting my current user and password and giving me a new one.
I forgot to mention that I made a full backup and a db backup on wp dashboard prior to the error occured.
I have both files on my computer with the extension .sgbp.
So sorry if I insist on this but since I can revert the problem by restoring to previous site and for that I only need a new access to the wp dashboard counldn’t you guys give me one? Please?
Many thanks
