I am building an Express application with nodejs and mysql. Most of the time I can make changes, restart the server and preview the site normally. But every now and again, instead of the landing page I get the following error page:
This site can’t provide a secure connection
c9users.io uses an unsupported protocol.
The client and server don’t support a common SSL protocol version or cipher suite.
I have not been able to establish why this is via Google and hoping somebody might know where I’m going wrong please?
