Problem: Trying to add a server to SharePoint 2013 farm, after a passphrase reset. Got this error message.
Failed to connect to the configuration database:
An exception of type System.ArgumentException was thrown. Additional exception information: Error during decryption. Ensure the passphrase is correct.
- Double-checked my passphrase is correct. If my passphrase is wrong, I should get this error message: “The passphrase you entered is incorrect. Please try again” – But I didn’t receive any such!
- Verified the pass-phrase change timer job’s last run time:
Get-SPTimerJob -Identity job-admin-passphrase-change | Format-Table -Property DisplayName,Id,LastRunTime,Status
- Tried restarting SharePoint Timer job and SharePoint Administration services in CA server
- Made sure the account I logged in is a Farm Admin account with Security Admin, DB Creator roles in SQL Server, and Local administrator in the server I’m trying to add.
Solution Worked for me:
Clear SharePoint Configuration Cache on ALL SharePoint servers! And rerun the configuration wizard in the new server!! Here is how: How to Clear SharePoint Configuration Cache using PowerShell?
