Windows Azure CDN using https - connection reset

Question

I keep having a problem where I'll randomly get connection resets when trying to access static content from the Azure CDN using https.

I have enabled HTTPS on the cdn endpoint and most of the time it works fine, but sometimes it's like it just hangs and no https links to the cdn works. If I change to http it keeps working fine and after about 10 minutes or so the https "comes back up".

Anyone else seen this or know what could be causing it?

This basically renders the CDN useless in my particular case.

Hi,

How do you enable CDN for static content in Azure application? I've tested it at my side but can not reproduce your issue, following the below link and have a try:

If you still get the same situation, i suggest you contact our support to make sure if your subscription works fine:

Hey,

Thanks for your reply. 

The CDN reads from a blob and works fine as long as I don't use https. It also works fine going directly to the blob link. 

Example: 

http://az167769.vo.msecnd.net/themes/trademarkdirect2/content/media/press/dailymirror1.png - Works all the time
https://az167769.vo.msecnd.net/themes/trademarkdirect2/content/media/press/dailymirror1.png - Works 99% of the time, but occasionally will just come up with a "connection reset" - and when it does it stays like that for ~10 minutes.  

I have tried deleting and re-adding the CDN to no avail. I do not have this problem on any of our other sites, though I hardly ever use https on those. 

Am I the only one with this problem?
