Failed to create gateway.

Hello!

All my data refresh failed today so I checked the gateway, it says it is configured correctly but the gateway is unreachable due to local network connectivity problems. So I followed some of the advice from the forum and unistalled the gateway and intalled the newest version. But then I can't retrieve it using the recovery key. 

I tried to create a new gateway, but it is having the same error:

Failed to create gateway. Please try again.

I found a post having similar issue but it doesn't have a solution.
