At first glance a few things stand out. Obviously you have a connection error (Connection refused). Assuming you are sure your internet connection is stable, did you verify in your terminal that you can reach ocsp.apple.com on port 80? I just tried it on my machine and it works.

% curl --verbose http://ocsp.apple.com/ocsp03-applerootcag3
* Host ocsp.apple.com:80 was resolved.

If it is an intermittent problem, you should add retry with exponential backoff or otherwise queue it for later.
