WunderGround says my PWS is not responding!

One of the sites I up load to is WunderGround. Have never looked at the settings since set it up about 4 years ago and now it says that the PWS is not responding!

The http://www.localweather.net.nz/smf/new-zealand-local-weather-network/49/
upload is working fine.
Any suggestions or should I go to their forum?
Many thanks

Within 5 minutes of posting on here it started working after 4 days

I get that messsage often. Lately I have not been able to get the WU app to to run, it says try later. I think it is a WU issue or internet issue. I had to reset my router yesterday.
