Users cannot connect to a child server when it's configured to disable storing the client credentials

In a multiserver environment, when the child server is configured to prevent saving client credentials (i.e.
"EnableClientCredentialsStoring none" is set in server.cfg), it is no longer listed among the available servers.

When a user with administrative privileges connects, he/she can see that such child server is marked as 'Unreachable'.

On the Cloud Server host, server log reports:
2537 2549 2021-01-07 15:28:13 465.241 ServerServerMonitor/ServerMonitor: ERROR! Unknown message 'NX> 198 Storing client credentials is not allowed.'

This problem has been reproduced with NoMachine v. 7.0.211


As a temporary workaround, disable direct access to the child server configured with "EnableClientCredentialsStoring none".

To do that, run on the Cloud Server host command:

nxserver --serveredit HOST:PORT --direct-access no

where HOST:PORT is the name of the child server, as it appears in the list of 'nxserver --serverlist'-


As an alternative, if users don't connect by the web, set "EnableClientCredentialsStoring webplayer" in the server.cfg of the child server where storing client credentials should be forbidden.
