Pritunl Single Host behind an Elastic or Network Load Balancer - Clients occasionally cannot route

I had a setup consisting of two hosts sitting behind an AWS NLB, where the OpenVPN connection is running on each host.

I had a few users reporting inconsistent connectivity issues - where they were connected but could not reach anything on the VPC.

I thought it was something to do with having two hosts, as when I narrowed it down to one host, the problem seemed to go away, however today it happened again with a user on the single host having to disconnect and reconnect.

Do you have any advice on where to check and what to look at given these symptoms?

I did have the port open so that the two hosts could talk to each other, and I have the setting for behind a loadbalancer enabled, but the issue seems to persist.

Thank you in advance!
