On Login screen, wont login "Login Failed"

Have SG 135 rev 2 with 16.5 MR7.

After upgrade the network is working just fine, but its impossible to login to the fw via GUI.

I have tried with smartphones, Mac OS, Win with different browsers. both via lan and wan (have certificate on wan)

As the login screen is shown, I type in user name and Password and nothing happens. It like the login button is not working.

I can login via Console, and I have been able to revert to 16.5 MR 7. Upload 17Beta1 again with same result.

 ***Update*** after about 2 min after i type in my credentials I get Login Failed
