    I had a similar problem ...

    * Upgrade to Plesk Onyx 17.8 failed with the following error:
    MSI: Error! Critical action 'Updating internal MySQL configuration...' failed:
    Command D:\Parallels\Plesk\admin\bin\mysqlmng_adm.exe --add-super-user "--login=admin" "--password=* "--allowed-host=localhost" failed with code 1.

    at execute D:\Parallels\Plesk\admin\bin\mysqlmng_adm.exe --add-super-user "--login=admin" "--password=*" "--allowed-host=localhost"(vconsoleapp::run line 110)

    * Plesk interface is not available with the 500 error.

    * Unable to access Plesk database:

    Hello, @Daniel Zampili de Souza.

    In case you are seeing the exact same error message, then solution from the article should help. In case you have any doubts or difficulties with applying it, let me know what exactly is not clear.

    However, in case you are seeing the error 500 and no other symptoms match, then I suggest checking this troubleshooting guide: https://support.plesk.com/hc/en-us/articles/115002513965--HUB-500-Internal-Server-Error-on-Plesk-server#plesk
