[network-health] Bridge status

[Bruno Grossmann]

Hello,

I have installed a bridge in December 2021. It has been running 
seamlessly - until recently. For the last week or so, when I check the 
status page, it says it is down. Yet, when I check on the server, it 
seems to be running fine (see output below). Is it an issue with the 
bridge checking mechanism or is there a real issue with my bridge? In 
other words, what information would I be looking for to ensure my bridge 
is up?
