Cross browser cookie problem?

[modules]

If i start from http://domain.tld/blog and want to login the form loads without an issue (through https://ssl.webpack.de/domain.tld/b...). After clicking sign-in i got a message that there is a problem with cookies.

I suppose this is about crossdomain cookie?

I am able to login if https/ssl is disabled. Also checked if i disabled cookie support: thats not the case.

My setup:

WordPress is installed in a subdirectory /blog and reachable via main http://domain.tld/blog

The hoster provides an ssl proxy and the blog is accessible via https://ssl.hoster.tld/domain.tld/blog

Plugin Setup:

SSL Host: ssl.hoster.tld/domain.tld/blog
Force SSL Admin: enabled
Proxy: Yes

Everything else is default.

Debug outtput:

[BEGIN WordPress HTTPS Debug Log] (index):140

event.returnValue is deprecated. Please use the standard event.preventDefault() instead.

Any help about it?

The issue probably exists somewhere around here in the code: https://github.com/mvied/wordpress-https/blob/master/lib/WordPressHTTPS/Module/Core.php#L643

I've seen a couple of other users with issues related to these cookies in more complicated setups.
