> I followed your documentation, how to put a known_hosts record into the
> connection profile (Public host key (Base64)), tried following:
> {code:java}
> testpc.test.com ssh-ed25519 XXXABCDEFGHNVjaOK+MgqlZSHPoNHHpuptJAOxYW6o
> ssh-ed25519 XXXABCDEFGHNVjaOK+MgqlZSHPoNHHpuptJAOxYW6o{code}
> however the result has been always:
> {code:java}
> guacd[1531]: INFO: User "@03827a1f-b013-4d5c-afdb-6cb08f19e56b" joined
> connection "$2df823fa-d766-40e8-8f1f-f7dae923dc2d" (1 users now present)
> guacd[1531]: ERROR: Host key not found for testpc.test.com.

> I tried to put also "ssh_known_hosts" file into GUACAMOLE_HOME with the same
> records, however, the file gets ignored... and it's same as if I don't setup
> any key. They connection establishes, but without any verification.
> {code:java}

> Is there a way to fix this please? I also tried increasing log verbosity with
> {code:java}
> -e LOGBACK_LEVEL=DEBUG
> {code}
> on guacd container, but it did not make what it was supposed to do. Thank
> you, any advice apreciated.
