OpenWeatherMap behind a proxy

Tags: #<Tag:0x00007f2fbbe47c70>

Hello everyone,
my OpenHAB installation runs behind a proxy. I configured the proxy host and port in setenv.bat:

set EXTRA_JAVA_OPTS=-XX:+UseG1GC ^
  -Djava.awt.headless=true ^
  -Dhttp.proxyHost=10.***.***.***^
  -Dhttp.proxyPort=8080 ^
  -Dhttps.proxyHost=10.***.***.***^
  -Dhttps.proxyPort=8080

I think, that works for me, because OpenHAB can download bindings from internet.

Sadly OpenWeatherMap stays offline and shows an COMMUNICATION_ERROR. A look into the log file brings to light that the OpenWeatherMap request generates a timeout:

16:24:53.780 [DEBUG] [enWeatherMapWeatherAndForecastHandler] - Initialize OpenWeatherMapWeatherAndForecastHandler handler 'openweathermap:weather-and-forecast:api:hamburg'.
16:24:53.780 [DEBUG] [enWeatherMapWeatherAndForecastHandler] - Rebuilding thing 'openweathermap:weather-and-forecast:api:hamburg'.

        at org.eclipse.jetty.io.CyclicTimeout$Wakeup.run(CyclicTimeout.java:271) ~[?:?]

It looks like the jetty client runs in a timeout, even through the requested url is correct. If I use this url in my browser with the apikey and location, the JSON response is plausible.

My question is: Uses the jetty client the proxy from the JVM environment or do I have to configure the jetty client proxy separatly by myself? Or is jetty ignoring the proxy in general?

Any solution here? I have the same problem…
