Whether one of those has inadvertently impacted your ability to connect to RDP servers behind a load balancer, I cannot say at the moment. You can see the full release notes for 1.6.0, below, and look for anything related to the issues you're having. https://guacamole.apache.org/releases/1.6.0/ I see other posts in mailing lists who have similar issues. > > https://lists.apache.org/[email protected]:2025-6:RDP%20server%20closed/refused%20connection > > You've posted a link to a general search of the mailing list about servers refusing connections. Those are all very different situations. You need to provide more detail on your environment and issue and what you've attempted to do to resolve the problem. -Nick >
