javax.net.ssl.SSLHandshakeException: java.lang.IllegalArgumentException: Invalid input to toASCII: ip_nbae7bac35.kodrive.xyz

Is there a workaround for this exception? looking at this issue on github it sounds like it might be an android bug, something about the hostname having an underscore character or something.

This is the stack trace:

Your issue is that you can not convert a string to ASCII using toASCII that contains an _. There is no way around this other than to get in touch with the owner of the domain and ask them to remove the _. This is why you got an IllegalArgumentException, the string was "illegal".
