Recently (about a month ago) we have added https to our web server. This was a requirement for the new v2 API, but it also allows us to browse the page securely. You can tell if you are using https by checking the icon at the left of the address bar.
Unfortunately there have been some issues with the transition that took us some time to catch. One possible reason is that it took some time for google to start directing people to the https version of the site.
– Registration. The captcha was not appearing when using https. Thus you could never prove you are a human even if you are. Should be fixed now.
– Uploading. Uploading sounds larger than 1MB failed as well on https. Fixed too!
With respect to 503 and 504 errors mentioned in the previous post, we are still working on it, but it’s looking good. We hope to restore the packs browsing page next week.
