Windows 10: Random SSL errors and connection timeout messages on many different websites/browsers

I get random SSL errors and connection timeout messages on many different websites. It was working fine until a couple of months ago. It makes the internet unusable. It is only on this Windows 11 machine which has been fully updated. I have a Windows 10 machine right next to it that works fine. Both have Ethernet not wireless connections to my router. It occurs on all browsers Edge, Chrome, Opera. I also use Thunderbird for my email and started getting random 'Can't connect to outgoing SMTP server' when trying to send a message. It occurred on different Gmail accounts. I had both McAfee

I cannot access secured ssl website to check email

Thank you for posting your query on Microsoft Forums.

I understand that you are experiencing issue with checking email on SSL websites after upgrade to Windows 10. I would certainly help you with this.

I would appreciate if you can provide us the following information to help us understand the issue better.

• What happens when you try to access the SSl websites? Do you get any error message? If yes, what is the complete and exact error message?
• Does the issue persists with both Microsoft Edge and Internet explorer?

If the issue appears with Internet Explorer as well, we can try clearing SSL state. let's try these steps below to do so:

Try to clear the SSL state from Internet Options and check.

• Press Windows key+R key to open Run prompt.
• Type inetcpl.cpl and press enter.
• go to the Content tab.
• Click on Clear SSL state and press o.
• Close and reopen Internet Explorer and check.

If the issue reappears, then do the following.

• In Windows Internet Explorer, click Continue to this website (not recommended).
  
  A red Address Bar and a certificate warning appear.
• Click the Certificate Error button to open the information window.
• Click View Certificates, and then click Install Certificate.
