I was having an issue with the weather app saying connection failed on my grandstream phones.  I reached out to grandstream to see what they say about this issue and this is the reply I got.

“The provider of the weather service -Yahoo-, used on the phones, has recently made a change to its API, causing the “connection failed” error or the service not to update. Our developers have been informed and will be working on an update for our phone series on a future firmware update”

When I get an update that they fixed this issue I will update this post!

If you have a fix please leave it in the comments below!

UPDATE: 8/1/2016

The fix for that issue is included in the BETA firmware version 1.0.7.65 available on firmware.grandstream.com. The firmware should be officially released anytime soon.
