Identify raison a certificate is not trusted

[svareg]

Hello, When we try to access our website from a computer (mac) where kaspersy is installed, the certificate is detected as not trusted. But for us, it seems that everything is ok : https://www.ssllabs.com/ssltest/analyze.html?d=oereb.bs.ch This happens only with kaspesky. Is there a way to find out the reason why my certificate is not trusted? Thanks, Guillaume.

When we try to access our website, from MAC, with KIS, the certificate is detected as not trusted. But for us, it seems that everything is ok: https://www.ssllabs.com/ssltest/analyze.html?d=oereb.bs.ch. Only happens with KIS. Is there a way to find out the reason why my certificate is not trusted?

Hello svareg / Guillaume, Welcome! Thank you for posting. Without knowing Mac Opsys version, build, KIS, version, build, patch(x) x=letter, please read the following; it may shed some light on the issue, noting, it's written for Kaspersky Security Cloud 19, however, some of Kaspersky's documentation can be applied across several generations of opsys & software. Website certificate problem detected by KIS/Mac and KSC/Mac If, after reading the documentation, you remain unsure & if you have licensed Kaspersky software, you may wish to consult Kaspersky Technical Support, for a definitive answer. Kaspersky Technical Support - Contact - select Location, select General product use, select from: OnlineChat - not available all regions. Phone - not available all regions Submit a request, via https://my.kaspersky.com/ (your) online account --- Additionally, it's possible to create an exclusion for your certificate, however, (imo), it would be good to know (from the Lab) why, KIS is "objecting" to the certificate, it may well be a false detection, something Kaspersky can fix, or, there may be a legitimate reason for the detection. IF the Lab finds the certificate is being identified incorrectly, they will assist by providing a solution. If the detection is valid, they will guide you with compliance steps. Please post back if we can help further, or, if you contact the Lab & get feedback? Best regards. Note: Kaspersky free software has (config) limitations, advertising & no Technical Support. If we know this, we ensure we never waste your time, advising you, for example: "contact Technical Support".
