After update to latest version my Mac (11.4) and iPhone (14.6) SSL certificate on my website is marked as invalid. All works fine on other Apple devices (with older soft version) and other devices.
Before update os systems this same website, with this same configuration worked fine on this same devices.

I looked for answer in network and check all params of SSL configuration but i don't found solution.
Apple shifted the certificate requirements with those releases, and some vendors—reportedly GoDaddy, GlobalSign, Certigna, and WidePoint—got caught out by the requirements changes.

Check with your certificate vendor for a replacement certificate, or switch to LetsEncrypt certificates.
