Hey mohamed2

Is it all websites where a secure connection is failing, or only specific websites?

Could you share with us the website address (URL) where the problem is occurring?

What are the exact error message(s) ?

Please provide a public link (no password) that we can check out. No Personal Information Please !

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

Disable your antivirus program. Does that fix it? If so, try uninstalling/reinstalling the AV program.
