Argo timeout error

Hi there !

I enable Argo tunnel just a few days ago. It run perfect for some time, but today I got some “500 Server Internal Error”.

I checked the Argo service tunnel and found the following errors:

I restarted the Argo service, and all was fixed.

What should I do in order to prevent future interruptions ? The error shows:

  • Serve tunnel error: Application error: 3002 connection dropped
  • Connection 1 unable to dial edge: DialContext error: dial tcp 198.41.192.7:7844: connect: no route to host
  • Connection 0 unable to dial edge: DialContext error: dial tcp 198.41.200.13:7844: i/o timeout

Thanks !. I need a solution so I can prevent future downtime.
