Craft 3 dashboard error
If you're running MAMP (and even if you're not, but it's common you are) and you're getting this error when connecting to Craft's web services:


  cURL error 35: Unknown SSL protocol error in connection to craftcms.com:443


Then you're running an older version of MAMP and you need to upgrade to the latest.

The older versions are trying to connect over https using an older SSL protocol (TLS 1.0) that is no longer supported.
