The skinUrl is invalid. You need the raw skin file not the rendered one.

from changeskin.

And what's the username of your uploader account?

from changeskin.

I looked at the source and it points back to this, right?

String oldSkinUrl = plugin.getCore().getMojangAuthApi().getSkinUrl(profile.getName());

from changeskin.

Yes and that is null, because the header field Location (for redirection) wasn't available.

from changeskin.

I guess profile.getName() returned an invalid username.

Anything I could try on my side?

from changeskin.

Yes, could you try the latest dev-build?

from changeskin.

do you have the bits or do I have to build?

"/skinupload url" returns a successful response, however skin selection only works for skins uploaded directly on minecraft.net. "/skinselect 12" returns a success message, however the skin shown is the last skin uploaded on minecraft.net

/skinupload http://imgur.com/a/FFwWE
issued server command: /skinselect 12

You have to use https://i.imgur.com/VpEebg9.png not http://imgur.com/a/FFwWE
