Over the past week we have received emails and calls from clients regarding their .gov.uk websites displaying an SSL Certificate error when using Internet Explorer or Microsoft edge.
This is an unfortunate side effect of the latest Microsoft update that you may have installed. Microsoft is working to fix the issue and had this to say:
“After installing the May 14, 2019 update, some gov.uk websites that don’t support HTTP Strict Transport Security (HSTS) may not be accessible through Internet Explorer 11 or Microsoft Edge,”
This is an error strictly on those websites which are .gov.uk but have no SSL Certificate.
These cumulative updates were supposed to introduce improvements for gov.uk websites, as per the official change logs:
“Adds "gov.uk" to the HTTP Strict Transport Security Top Level Domains (HSTS TLD) for Internet Explorer and Microsoft Edge.”
To help aid our clients through this issue, we are offering SSL Certificates at a price of £75 +VAT as opposed to the normal £125 +VAT. The only other alternatives are to use a different browser or wait for Microsoft to release a new update addressing and hopefully fixing the issue.
If you would like to take us up on the SSL Certificate offer, please contact email@example.com.
