No disk space left, (just Resize) but Plesk is still down and can't access SSH

Hello!

For the last week, my server has been running low on storage space due to the amount of files that are in it, and commonly the mail service crashed due to lack of space as well as not allowing to log in to plesk . Generally I would restart the server and fix it temporarily and this allow me to log into plesk to delete files and free up enough space to keep it running.

As a solution, a resize was proposed, however it took us 1 week to obtain internal authorization within the company. Now the issue is that we have just performed the resize, however plesk is still down (error 500) and now the mariabd service has been turned off so the websites hosted on it are also down. And plesk from the repair kit keeps mentioning that we only have 80gb total (of which there is nothing available, and it causes the problem) although we just increased to 160gb.

Also I cant connect to SSH via web console (to try fo free some space) because after recovering the root password and login, always tell me to change the password (enforced) and when I try, its tell me: Authentification Token Manipulation and I cant continue. (I know that I need to enter my current password first).

Server info:

8 GB Memory / 160 GB Disk / NYC3 - CentOS 7.6 x64

I would greatly appreciate any possible help
