  • Support for BIND DNS has been removed from Plesk for Windows due to security and maintenance risks.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS.

8.0 to 8.2 Upgrade Failure - cannot connect to MySQL

I have Plesk running on FC2. I went to Updater and click "install" for the default-checked items to upgrade from 8.0 or 8.1 (not sure). I received the log of the upgrade via email. Subject line: "Plesk autoupdate success report." However, now when I go to any of the websites on that server, I get a SiteBuilder dialog instead of the actual website. When I attempt to access Plesk (via browser), I get the following message:

ERROR: PleskFatalException
Components::componentUpdate() failed: Unable to exec utility packagemng: packagemng: Unable to connect to Plesk Database: Client does not support authentication protocol requested by server; consider upgrading MySQL client
packagemng: Unable to connect to the mysql database

0: /usr/local/psa/admin/auto_prepend/auth.php3:508

I went back and looked at the log that was emailed to me. I noticed the following: Trying to stop BIND server... done
dnsmng: Unable to connect to Plesk Database: Client does not support authentication protocol requested by server; consider upgrading MySQL client

After that point in the log, the "Client does not support authentication protocol..." message appears over and over and over again.

I desperately need to get these sites back up and running. Is there a way to fix this quickly? Or, is there a way to roll back the installation so that everything will work properly. Any help would be greatly appreciated!!
