Hi All, 

We are trying to edit an Auth Provider set (e.g. OpenID Connect) in our Sandbox environment however it returns the following error message:

Unable to Access Page
The value of the "Decryption Exception" parameter contains a character that is not allowed or the value exceeds the maximum allowed length. Remove the character from the parameter value or reduce the value length and resubmit. If the error still persists, report it to our Customer Support team. Provide the URL of the page you were requesting as well as any other related information.

Any help on this is greatly appreciated, thanks.
