Infopath Publishing error "The following URL is not valid"

When trying to publish Form the following alert appear "The Following URL is not valid"

Solution: 

After Googling and trying lots of things, I remembered my proxy was turned on at University...

Check if it's active, if so deactivate the proxy server at IE

Internet Options - > Connections - Lan settings - > "Proxy server" - deactivate the check boxes here

Have a great Day ;)
