If you have been suffering for days from the continuous inconvenience of not being able to access your Gmail, or you cannot access youtube/Facebook due to a DNS problem with an irritating message incorporated related to an insecure connection (a248.e.akamai.net certificate problem)

Update 03/12/2018 New Data!

As we suspected, it has been revealed that the reason for this failure is the end of support for SSL / TLS certificates from Symantec.

This process was started by Google Chrome some time ago with certificates issued before June 1, 2016 and will be completed on September 13, 2018 . After this date, all remaining Symantec certificates will stop working, including those issued after June 1, 2016, and will display the error message.

Therefore, from then on, the only solution will be for the affected websites to change their security certificate.

Symantec has enabled an SSL certificate checker to see if your favorite website will be affected. To highlight the text enabled on this website: «Check your website for the distrust of Chrome».

A check that corroborates this protocol change is if we look in this checker for the address “a248.e.akamai.net”. What happens is this:

Remember! The certificates affected by this Chrome compatibility change will be: Symantec, Thawte, GeoTrust and RapidSSL certificates
