The hashed password in the file /etc/psa/.psa.shadow, that is used to access Plesk database, does not match the admin password in the 'mysql' database.
Resolution
If the password for MySQL admin user is known

Make a backup of the file
/etc/psa/.psa.shadow:# cp /etc/psa/.psa.shadow /etc/psa/.psa.shadow.bak
-
Insert the new password in
/etc/psa/.psa.shadowin plain text:# echo 'new_password' > /etc/psa/.psa.shadow
Note: do not forget to replace the new password from the command by the proper password.
-
Set the same password using Plesk utility in order to store it encrypted in
/etc/psa/.psa.shadow:# PSA_PASSWORD=new_password /usr/local/psa/admin/sbin/ch_admin_passwd
Note: if this command produces some output, apply the 2 method.
If the password for MySQL admin user is unknown
