a group of 3 or 4 host machines.

Question: How are you connecting to the remote systems? VPN?
Answer: No VPN connections. The remote server in this case is accessed primarily
via TigerVNC or simple ssh sessions. The remote server is running Arch Linux.
My local host from which I make multiple vncviewer connections is also an
Arch Linux system.

Postscript: If I attempt a second TigerVNC connection from a seperate host
within my local network, it is successful. The connection failure only occurs
when attempting to make an additional connection from the same local host.

Thank you.
