From my limited knowledge, looking at the screengrab above it mentions 'failed to obtain lease' - this could be the issue with your ip address - try this;
open the command prompt and type
ipconfig/all
You should get a list of info, one of which would show the lease granted/expiry of your ip - if it is expired then you can release and renew it with the following;
ipconfig/release
ipconfig/renew
And that, in theory should work! Hope that helps
