3 months ago Found a work around on how to resolve the issue while preserving remote server connectivity & keeping my topology & nodes intact.
I'm adding this as a note for now for historical purposes, updating the bug link below with my work around if others face this issue:
IMPORTANT:
1) - Make sure you kill the gns3server 1st before you attempt to run gns3server --local from the CLI.
2) - If you don't know how to do that, go down below you'll see where I identify if the gns3server service is running and how I killed it.
3) - You don't need to run --debug but I did it to troubleshoot the issue to see if the server or client returned any logs.

<Yes>the following question. (if select<No>, this problem does not occur.)Use Systemd to automatically launch the GNS3 server at boot. Do you want to enable and start the GNS3 server as a service?
