After starting SLES 11 SP3 or SP4 instances in AWS (region eu-central-1), the suse_register executed during cloud-init is not working.
The error from /root/.suse_register.log returned after the send to https://smt-ec2.susecloud.net/center...mmand=register.......

HTTP/1.1 500 Internal Server Error
Error message:
<br />Apache2::Filter::get_brigade: (70007) The timeout specified has expired at /usr/lib/perl5/vendor_perl/5.10.0/SMT/Utils.pm line 299

As the result, there are no repositories registered (except the NVidia) and it's impossible to install any software.

Thanks in advance for your help,
