A 503 Service Error is a common type of error where the service remains temporariy unavailable. There are multiple reasons why you may get this error. In Plesk, this is what the error message reads:
When you check the error log from the Plesk control panel at Domains > Domain.com > Logs, you will find that there are no logs. Furthermore, you may notice a couple of other things. If you navigate into IIS Manager > SERVERNAME > Application Pools and open the PleskControlPanel Application pool, you’ll notice that the pool has stopped working. Even when you open it manually, it will still stop.
If you open the Event Viewer Application, you may get an error message like this:
The worker process for application pool 'PleskControlPanel' encountered an error
'Cannot read configuration file due to insufficient permissions
' trying to read configuration data from file '?\C:\inetpub\temp\apppools\PleskControlPanel\PleskControlPanel.config', line number '0'.
The data field contains the error code.
Fixing the Error
More often than not, the error results because of a corrupted Plesk configuration file at: C:\inetpub\temp\appPools\PleskControlPanel.
Here are the steps you need to take to fix this error:
Using RDP, connect to the Plesk server
Rename the config file at C:\inetpub\temp\appPools\PleskControlPanel
Next, navigate into Plesk Reconfigurator at Windows Start > All Programs > Plesk
Here, click on Repair Plesk Installation and Select Check for Check Plesk Services
Using the following command restart IIS:
iisreset /restart
This should fix the error. Now when you open Plesk from the browser, you shouldn’t get the 503 Service Temporarily Unavailable error. For more assistance, get in touch with the customer support team.
