> After about 60 connections, the oldest connection will be closed to open the new connection.
> In the logs, we can see a similar issue mentioned in [GUACAMOLE-1920] When the cumulative number of user connections reaches a certain amount, guacd will report an error. "RDP server closed/refused connection: Security negotiation failed (wrong security type?)” - ASF JIRA

> Version 1.5.3 seems to work fine with >100 cumulative connections tested on the same environment.
