I have a site on shared hosting.
When I did an SSL Labs test, it got a grade of “A” but two certificates showed up and it says my site only works in browsers with SNI support. The first cert is the one I installed and the second is a “no SNI” certificate for another website that appears to be on the same shared server at my hosting provider (same IP address and is using same hosting provider and DNS, so am guessing we’re on the same server as well).
When I do an SSL Labs test for the other person’s second site, everything seems fine - my cert doesn’t show up on his test results and his site works on browsers without SNI support. His main certificate has a fingerprint that matches the “no SNI” cert that appears in my test results.
Does anyone know why I’m getting info from his certificate on my test results but he is not getting info from my cert in his results? Is there anything that can be done to fix this?
