My Problem
Today when I tried to deploy my sandbox solution I suddenly got the following error:
Remote SharePoint site connections are not supported.
The site I tried to connect to was http…..spsite.mydev.local and this definitely is on my local machine.
Your Solution
Earlier today I updated DNS and removed the entry from my local host file.
I added the following in my host file:
127.0.0.1 spsite.mydev.local
So it looks like Visual Studio doesn’t like connecting an IP address that isn’t 127.0.0.1
