Why am I getting an error message in Service Configuration: "We are unable to process your request at this moment."?

"We are unable to process your request at this moment." error message appears when trying to access Service Configuration.

This error can occur for multiple reasons.

Please make sure that you are on the right URL. You should be logging in from https://www.worldcat.org/config. Adding additional characters to the URL can cause the error described.
Are you logged into WorldShare within the same browser window? If so, open Service Configuration within a different browser's window (i.e. if WorldShare is open in Firefox, then open Service Configuration in Chrome).
Check the roles that are assigned to your WorldShare account. This page lists the roles available in the Admin module that allow access to the OCLC Service Configuration: Service Configuration roles
If your institution is not set up for WorldShare Interlibrary Loan or WorldShare Circulation, you will have to use your WorldCat account to log into the service config.
If the issue persists after these checks, it may be related to environmental factors such as network or firewall restrictions. In some cases, institutions have identified firewall configurations that block access to Service Configuration. If you suspect this, please continue working with your local IT team. They may need additional information from OCLC, and we are happy to assist with any questions they have.

If this does not resolve the issue, please contact OCLC Support using the username you use to log in to the OCLC Service configuration.
