As of 22 August 2015, 4:59:59PM, the SSL certificate for discuss.appium.io will expire. Perhaps by the time you read this, it already has.
We at Discourse are working with Appium to get a renewed certificate as soon as possible. In the meantime, you will either have to discontinue use of the site, as all of our hosted sites with SSL use HTTP Strict Transport Security; or use an alternative browsing method.
Rest assured that we have taken, and will take, steps to prevent this from happening again in the future. When Let’s Encrypt is in general public availability, we will most likely be providing basic SSL certificates (like the one Appium has) for free.
Admins - feel free to close this topic as soon as you get the new certificate submitted to us.
