Dear Tailscale Developer,
I have came up with a bash script with runs every 15 minutes on crontab scheduler job to ensure that if TailScale loses connectivity to Internet it will reestablish back again!
You guys should code it into the binary of Tailscale to checks for WAN link every minutes to ensure this problem of not reporting to TailScale Server does not dies endlessly.
Here is my code logic to temporary resolves the issue on two WAN link acting as backup failover.
The problem is once both WAN link is down Tailscale just is not smart enough to establish it’s link back to the central TailScale Server.
Why can’t a check WAN IP be initiated every minute to avoild this enless dead connection problem?
Thanks.
