hello,

after a while i get this error here:

2018-01-29 17:56:00.897 [ERROR] [org.openhab.io.net.http.HttpUtil    ] - Fatal transport error: java.net.ConnectException: Connection timed out (Connection timed out)

2018-01-29 17:56:00.901 [ERROR] [ab.binding.http.internal.HttpBinding] - No response received from 'http://192.168.1.15'

after this, my item becomes no update, no new values. i read my values with

Number Gaszaehler               "Zählerstand [%.1f m³]"         <gasuhr>    (Gas)            { http="<[http://192.168.1.15:60000:JSONPATH($.Wert)]"}

what is the problem?

the side http://192.168.1.15 works, and give me my gas meter values in JSON Format:

{
"Wert": "28989.54",
"SSID": "FritzRouter",
"IP": "192.168.1.15"
}

where’s your openHAB running from? I guess, this machine don’t have access to your gas meter server.
if it’s a pi or linux, please login to the shell and try wget -O gasmeter.json http://192.168.1.15, it should immediately give you the response and you should see the JSON saved as gasmeter.json. If not, it’ll tell you some error-message.
My guess is, you’re not allowed to access the gasmeter-server from your openHAB instance.
