As per PM from .
At least some Android devices do not seem to resolve their own local host addresses properly (every distro is different) meaning that Android can’t act as a server. I don’t have an Apple device on hand, but looking at the source code IOS should work fine.
Whether mobile devices have the CPU performance to act as a server is a separate question/issue.
I have issued a pull request on github that fixes the ‘Android unable to resolve local host address’ issue.
