Redundant Gateway Duplicate Connection Error

Hello,

We are doing initial setup for a new project and trying to connect an redundant pair up for a gateway without using SSL.

I have the IPs set up as .110 and .111 with the ports set to 8088 and SSL disabled, but am still getting an error where the gateway network connection faults due to a duplicate connection on the backup gateway and does not show up as an incoming connection on the master gateway:
Remote server rejected web socket: Duplicate connection

Both of these gateways are on a proxmox linux system with the same machine ID, but the uuid, gateway name, hostname, and IPs are all different from one another.

Does anyone know of any other things to look for that might be causing a duplication issue or whether the machine ID could be what is causing the issue? Any information is greatly appreciated.

Thank you!

Are you trying to make an outgoing connection from both the master and backup, or anything like that? Have you restored a gateway backup or duplicated a VM aanywhere else in the network that might be conflicting?
You're sure the UUIDs are different, and before attempting redundancy both are set to a unique system name?
