Pritunl wireguard client does not respect host "Sync Address"

Pritunl Pritunl VPN

We use a separate host to provide web UI access/profile retrieval on port 8443. When a user first connects with WG the Pritunl client attempts to connect to the server host IP instead of the host’s sync address value. A unique symptom is the sync address in client logs is Server Host IP:8443 instead of the Sync Host Address:8443.

We’ve used the web UI:8443 for profile sync/retrieval for a while. This is the first time we’ve had a problem like this.

Here are the logs, IP addresses have been modified.

Sync Address - vpn.example.com:8443
Server Host - 192.168.1.2

After I remove the sync address from the host and reimport the profile,

The sync addresses are added to the host addresses and all of these are iterated in a random order. It should continue to iterate until a successful connection is made. I may change the code to iterate sync addresses first but these logs seem to indicate both your host and sync address are inaccessible.
