upgrade from 18.0.7.132 to 18.0.8.912 = unable to login to management console -> server error

[kwen1x]

started upgrade from linux console (ssh, root login).. no errors.
Even phones are still working after upgrade.
BUT management console refuses login: server error.

Have rolled back from backup, redid upgrade.. same story.

Now what ?

Difficult to say, I'm sure at least on V16 it was enforced.

I think we are running since 2017 -> V14
So that might be explanation of password being too long...
