Environment:

B2C Service Chat
Customer Portal 

Did you recently move to Customer Portal (CP) version 3.7+?

If yes, read on.

Are you having problems with chat authenticating?

If yes, read on.

Are you receiving the error message “Failed to load resource: the server responded with a status of 403 (Forbidden)”?

If yes, read on.

Issue:

At this time, the following error appears within the Console tab:

“Failed to load resource: the server responded with a status of 403 (Forbidden)”

Some customers on CP version 3.7+ may experience an issue where chats are not authenticating. You may encounter the following:

• Open a browser console 
• Select the Console tab 
• Create a test chat 
  • Do not login 
  • Complete the form (if required) 
• Submit the chat 

Resolution:

This error occurs when the configuration for CP_CONTACT_LOGIN_REQUIRED is set to one (1). When set to one, CP_CONTACT_LOGIN_REQUIRED will prevent chat sessions from entering the system.

To remedy this issue, set the configuration for CP_CONTACT_LOGIN_REQUIRED to null (0). If you require authentication for non-chat related pages, then you should ensure that the login_required = true on the page level.​​​​​​
