Perhaps you have more than one Red Hat username you can try? Did you use the same one to register for the Red Hat Learning Community? I just tested the registration process and was successfully able to access the course within 10 minutes. If you still have no success DM me your username and I will try to assist.
Guys, Please use your Login ID or Username which you have given while registering. Please note dont use your Email ID else it will show 0 course inside the catalogue. So please ensure to use your Username name. If forgotten, then check your 2nd or 3rd mail from firstname.lastname@example.org, then access it.
I have always used my email address as username to login. That's why I forgot about the username. Today I check for any other username that I've created for this account and found one. Using that username to login, now I can access the course. I missed that all this time and now I only have 19 days left to complete the course.
Thank you for the support.
