Angel, another person in this forum reported Error #500, which means internal server error. Give the rol.redhat.com another try, perhaps even with another browser, it may have been a temporary issue. I'm using rol.redhat.com learning website now.... However....

To add the procedure to open a case as ir. Jan Gerrit Kootstra appropriately recommended, here's the steps...

• Go to this link: https://access.redhat.com/support/cases/, which is at the top of this page too, named SUPPORT CASES.
• In the Product drop down, select: Red Hat Online Learning (NOTE: You will need to scroll down through a list in the drop-down menu)
• Important, in the Product Version drop down, select the largest number (as I type this, it is 1.0, but that may change over time) NOTE: the "Submit" button won't activate until this is selected.
• In the Case Type drop down, select: Other
• In the Problem Statement block, enter something concise, the course number, and a small description.
• In the Case Description block, enter the specifics.

The other blocks are straightforward enough. When I've submitted a ticket for Red Hat Online Learning, I make it a low priority, it certainly is not production. One of the course administrators does on occasion check the forum, but you ought to submit a ticket for this issue since this is supported.

The Training Principal Product Manager also highly recommends submitting a case for this, as the experiences of one customer in resolution may not necessarily work with another (paraphrasing) see this link, it leads to his comments
