Error: Cannot activate plugin because of: SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

When you see this error when you attempt to activate Patchstack:

  1. Check, if your server is using TLS 1.2 protocol activated. You can easily test it here: In case it is disabled, you should activate it in your hosting environment.
  2. Ask your host to upgrade cURL/OpenSSL on your server to the latest version.
