Firefox 29 and up: “The connection has timed out”
Posted by jpluimers on 2019/04/24
A few years ago, Firefox changed the default “network.http.response.timeout” value from zero to 300 seconds (5 minutes).
Display style systems that show refreshing web pages, this can be a problem as when the connection to the web-server is unavailable for more than 5 minutes, then the page will show “The connection has timed out” and stop refreshing.
The solution – apart from fixing each and every connection problem – is to either restore the value or make it very long:
network.http.response.timeout=0network.http.response.timeout=30000
Changing this works similarly like in A way to skip the Firefox “Well, this is embarrassing” during a sudden reboot « The Wiert Corner – irregular stream of stuff:
