After I click on download, Firefox won't proceed & states your website isn't secure & configured improperly. Won't proceed to prevent information from being stolen. Care to comment?

I've had this calendar in my mac calendar for a while now and it's now indicating an error. If I try to subscribe again I get an error message that says: "There was an error subscribing to the calendar.The data downloaded from webcal:// isn’t valid."

Hey Ryan, This calendar wasn't able to sync on my Mac anymore. I tried to pick up on your good work here by publishing a similar calendar here on iCalShare. It's listed as "Seasons, U.S. Eastern Standard Time through 2050." Thanks for providing us with this data for many years. Cheers, Tom
