Two things to check if going from the welcome page to the login page is THAT 
show.

1. Make 100% sure your DNS is setup correctly (or your /etc/hosts if that is 
what you use). If the engine cannot resolve itself, it will create lots of 
issues.
2. If you are running hosted engine, make sure you have enough entropy, the 
login page generates a couple of tokens using secure random, which eats away 
at your entropy budget heavily and since hosted engine is a VM it is possible 
that you don't have enough entropy. You can check your entropy level with 
this:

cat /proc/sys/kernel/random/entropy_avail

There are several options for solving the entropy problem if that is the case.
