Upgrade to Version 11.1.16.0 broke server

[serpher 2]

After upgrading server to 11.1.16.0 from:

ESET PROTECT On-Prem (Server), Version 11.1 (11.1.756.0)
ESET PROTECT On-Prem (Web Console), Version 11.1 (11.1.144.0)

Connection to database broke and ESET web console and ESET Inspect could not log in with this message:

Quote

Login failed: Connection has failed with state "loginConnectionStateNotConnected"

ESET server is on Debian 11. I could connect manually to the database on the server.
