Service Desk Portal URL is incorrect after changing Project Key

Hi,

We changed a project key and the linked JIRA Service desk configuration area is accessible. However when clicking on the customer portal link it still references the old project key and not the new one.

Is there a way of changing this? I don't see anything within the JIRA UI.

I did try to disable service desk and re-enable to no avail.

Many thanks

Darren
