Clarity 503 Error on Host

Reboot the machine after upgrading if you haven’t done so already, this may fix the issue.

The 503 Error means there is an issue with the application pools, typically this means they aren't running and the most common reason is the credentials.

Log onto the host machine as the Clarity service account

Check the Application Pools
Open IIS (Internet Information Services)
Select Application Pools on the Left

There are three Clarity application pools
Right click on each one in turn and stop the service if it is running

Right click again and go to Advance Settings

Select Identity then select the ...

Select Set

Enter Domain\Credentials and password


OK out of all dialogs.
Repeat for all Clarity app pools
Start the app pools

Test the Clarity web portal connection.

It will be stressfully slow to connect the first time after restarting the application pools...but it should connect.

If there are still issues, zip the content of the logs folder and send that in.

C:\ProgramData\IMAGINiT Technologies\Clarity\Logs

If the issue is on the task server, open the Clarity task tray, go to the Logs tab and send in the diagnostics.
