Hi, @itshaisam, and welcome to the Netlify community site. 
In order to troubleshoot, we need to track down what is happening when your browser makes that request. We need the more information about the request in order to do that.
The simplest way to do this is to send us the x-nf-request-id header which we send with every HTTP response.
There more information about this header here:
If that header isn’t available for any reason, please send the information it replaces (or as many of these details as possible). Those details are:
- the complete URL requested
- the IP address for the system making the request
- the IP address for the CDN node that responded
- the day of the request
- the time of the request
- the timezone the time is in
Now, if SSL negotiation is failing, then it is almost certain you won’t receive any headers so the details above are remaining option.
We look forward to researching this in more detail and please free feel to add additional questions anytime.
