Unable to unlock module 2

I completed all the tasks in module 1 and also got the build success feedback. Even then I am unable to access Module 2.
I waited around 3 hours waiting for it to unlock.

Some server error.

Its working fine now. Check it now

Still unable to unlock module 2.

is your last milestone of module 1 marked as complete?
If yes,try restarting your browser and logging again!
