Hi Cisco,
I have the same problem after upgrading to 2.7.3.1 from 2.7.2.5.
Upload fails with reason: The tail-end gateway is not registered yet.
Possibly due to CSCvh60290.
But. I also have a problem that I´m not able to replace the entitelment certificate in the collector. I downloaded the existing certificate from services.cisco.com, and tried to apply that.
And it fails with the following error message in the collector:
Failed to apply the registration certificate file or to apply service specific patches. Please check the logs.
I have not yet tried to generate a new entitlement certificate and try that.
Please advice if if should generate a new cerificate and try to register with that.
Best Regards
Sven Hansson
