I have recently downloaded and installed SLES 12SP1 and attempting to register the 60day trial/eval code that was provided. However, whether I use Yast, or SUSEConnect, and whether I use my email, or my userID, I receive the same results:

Error: SCC returned 'Unknown registration code.' (401)

I have attempted this with 2 different evaluation codes, same results for both. When attempting to Manually Activate a subscription through ssc.suse.com neither code returns as valid either.

I'm very new to Linux in general, but the process for RHEL registration was fairly straight forward. I'm doing this as a comparative installation for an application I need to install and test. Any assistance would be most appreciated.
