Wow!!! Best regards Hendrik!!!
Most probabily the provider's router is buggy but it solved
the problem.
The solution was that reported by article pointed by you:

In the mean time, anybody running a current kernel who is
having trouble connecting to a needed site can work around
the problem with a command like:

    echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale 

or by adding a line like:

    net.ipv4.tcp_default_win_scale = 0

to /etc/sysctl.conf.
