Trying to subscribe to my own photo stream through email?

I am trying to test and basically learn more about photo stream and sharing through email. So I send a test photo stream to my own email (one of many emails but all are attached to my name) and when I click 'subscribe to this photo stream' I get a prompt to join, I click join and then I get the below error message? Does anyone know if this is because I am trying to subscibe to my own photo stream or do I actually have a problem that needs to be addressed? I have waited up to 30 minutes to give it more time but always get the same error message. Thanks!!
