h2o Flow UI not working - python-2.7

Question

I recently upgraded to H2O-3.11.0.3820. My web based flow ui is not working.
When I go to the link, i get a light blue colored screen with all the options that I used to get earlier, missing.
Unable to find anything relevant on stackoverflow. Any one else facing similar issue? Any help will be much appreciated!

Answer 1

As you discovered, install a stable release of H2O-3.
Nightly builds are number 3.ODD.y.z
Stable builds are numbered 3.EVEN.y.z
(So 3.11.0.3820 is a random bleeding edge build, not a stable build.)
