Problems accessing Red Hat Software Collections again

Hello,

Two months ago I opened a discussion because I was not able to access rhsc despite I had a "Red Hat Enterprise Linux Academic Server, Self-support" subscription
You can see it on https://access.redhat.com/discussions/2700971

It solved suddenly and I had access to rhsc again. Yesterday the access to rhsc failed again so I have the same problem that was described on the previous discussion. The point is that my subscription ends on the 7th of March of 2017 so I don´t understand why it has stopped working again. Searching for a solution on RedHat Portal I have found this:

https://access.redhat.com/solutions/472793

"Customers with the following RHEL subscriptions can get access to RHSCL and DTS for free, but may need to initiate a special request for it:

Red Hat Enterprise Linux Server, Premium
Red Hat Enterprise Linux Server, Standard
Red Hat Enterprise Linux Workstation, Premium
Red Hat Enterprise Linux Workstation, Standard
Red Hat Enterprise Linux Academic Server ------> This is our subscription
Red Hat Enterprise Linux Academic Workstation"

I have just made a request to www.redhat.com/wapps/try/RHSCL to try to resolve the problem. Anyway I don´t understand the following:

-If my subscription is active and I had access to rhsc, why does it stop working suddenly? Perhaps the access to rhsc is deactivated automatically after sometime and I need to request access to it again periodically until the end of the subscription? If this is the case it doesn´t make sense for me and I feel that is nonsense

Could anyone give me an explanation as well as some help about this problem??

Thanks in advance

Steven
