It remind me of one weird bug. The corrupted ssl keystore(due to some
encryption/decryption of db which I don't understand well, I remember
Kelven knows more about it) on mgmt server make it impossible to connect to
mgmt server.

Could you clear "ssl.keystore" entry in configuration table of db, as well
as cloud.keystore file in the configuration path and restart the mgmt
server and try again?
