Follow step by step on this trailhead module.

I am stuck on this part where it instructs us to : '10. Click Start Wizard to begin the setup wizard.'

The error message I got is as below :

Remote Site Setting Missing Web service callout failed: WebService returned a SOAP Fault: INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session faultcode=sf:INVALID_SESSION_ID faultactor=

As shown in this screenshot :

Any ideas how to resolve issue?


Session ID usually refers to the login session, so I would (1) Ensure that the integrations users are setup correctly and all the steps leading up to "Connecting the clouds" are completed from the guide.

Then, log out of everything - both MC and Core.

Then, with API user credentials, log into MC and log into Core.

Try again - this should resolve it.

In case it doesn't, you can try to manually verify the remote site: https://help.salesforce.com/articleView?id=mc_co_advanced_faqs.htm&type=5
