Hello,

i have a internal site where firefox shows an ssl_error_bad_cert_domain error. When i view the extended information, it told me that the certificate dont match to the site. But there is also an list of sites that are supported by this certificate, and this list includes exactly the url iam calling. Btw. all sites are included in the SAN attr of the certificate. There are other sites included in SAN that worked fine.

If i call the same site with IE11 it works fine as well.

Have someone an idea why firefox (68.2.0 esr) dont recognize the site?

Thanks!

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

There is no security software in use (only win defender). And some sites from the SAN attribute works fine, so if this is caused by security software i would except that no site from this certificate works.
