Server Does not Connect to Bridges after Network Outage

[pedramezzati]

hi all
I have a problem with my softether vpn setup, I set up my server (windows) to connect to 3 remote location(bridges) windows as well , all devices connected to the bridges are working and getting ips without any issue.
my issue is that yesterday there was 2 network internet outages server side, when the internet is back up again, the bridges can not connect back to the server for some reason, when I restart the server completely, the bridges connect automatically, so the issue isn't from the bridges cuz it connected as soon as the server was restarted.
how can I fix this issue.
is there an option i forgot to enable to make the server go online automatically?

thanks in advance

If your bridges depend on VPN Azure or NAT-T, they'll be unreliable.

I use Layer 2 bridging, not Azure.
My temporary solution to this issue is to run the SoftEther VPN Server inside a VM. I’ve configured a PowerShell script to run at startup via Task Scheduler. The script pings my public IP every 30 seconds: if the ping succeeds, it continues monitoring; if it fails (indicating internet outage on the server), it waits 30 seconds and try again, if it fails again then forcefully restarts the VM.
I tested this setup and it works for now.
Is there a simpler solution?

Again, if your "Layer 2 bridging" bridges depend on VPN Azure or NAT-T cascades, they'll be unreliable.
