I tried the BigBro appplication and set the following config:
services:
- name: My Server
protocols:
- type: https
server: servername
interval : 120000
This results in a timeout and the server is constantly shown as offline. For me a ping every 1-2 minutes is enough, which is why I did it not set to a lower interval. If I set the interval to 5 seconds (5000), it works without any problems.
Error message is meet error: websocket: close 1001 (going away)
