authorization failed while uploading to SVN (svn.wp-plugins.org)

I don’t know if this is the right place to ask, but I’ll give it a go.

I try to upload/commit a new version of a plugin, but get authorization failed.

This is the error I get;

svn: Commit failed (details follow):
svn: CHECKOUT of ‘/!svn/ver/25761/wp-gravatar/tags’: authorization failed (https://svn.wp-plugins.org)

For the record, I’m 100% sure that the user/pass is correct!

Any ideas? Or any ideas on who/where I can redirect this question?

Thanks for any and all help!

Regards,
Rune
