NET::ERR_CERT_REVOKED only on my Mac, what to do?

Welcome! Recently encountered a very strange problem on my Mac and Iphone(Only on my devices, the rest are all working well).
The problem is that when you visit one of the resource I get the error NET::ERR_CERT_REVOKED and I can't access the website from their devices. Not only that I tried:

• Changed different networks (wifi, 3g/4g)
  
• Rechecked the time and date 20 times and disabled/enabled the automatic update of date
  
• Contacted Apple tech support, but from them I got the same advice that he himself had experienced it
  
• Add certificates to KeyChain and so on
  

What could it be? If it was a virus on my Mac, on the iPhone everything would work
Please tell me, what are the options diagnosis?

In all browsers the problem is the same
