"This site works only in browsers with SNI support."


I’ve run my site through the test at SSL Labs:


Although they give it an “A” rating, there’s a line that says:

This site works only in browsers with SNI support.

Then, further down, under Handshake Simulation it seems that my site fails for:

Android 2.3.7
IE 6 / XP
IE 8 / XP

Given the number of XP systems still out there I think I need to fix this, yes?

What do I need to do to fxx this with Let’s Encrypt certificates please?




For browsers that don’t have SNI support then you need a dedicated IP address (for your domain only )


All domains behind must use the same certificate to work without SNI.


Thanks for that.

In the meantime I’ve been looking further at the stats and XP usage is much lower than I remember it being when last I looked. And IE 6/8 usage is nowhere to be seen, so perhaps this job is not high priority:


Stick with SNI. IPv4 addresses are a precious commodity, and for anyone still using Windows XP / IE LTE 8, https should be the least of their security concerns.


You don’t need an ip address for every domain, just one for every certificate, and certificates can have multiple domains.
