My users recently started receiving SSL error when clicking on link protected email links.

 

Chrome states: The site can't provide a secure connection  linkprotect.cudasvc.com sent an invalid response  ERR_SSL_PROTOCOL_ERROR

Edge state: Hmm, we can't reach this page

Firefox states: Secure Connection Failed   Peer received a valid certificate, but access was denied. Error code:SSL_ERROR_ACCESS_DENIED_ALERT

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the website owners to inform them of this problem.
 
Not sure how to resolve the issue. I've tried several suggested fixes but nothing has worked.  I have tried to:
• Disable QUIC Protocol
• Clear SSL State
• Update System Time
• Check Firewall Settings
• Disabled Browser Extensions
• Disabled Anti-Virus.
 
If we can't resolve this, I will have to disable linkprotect.

Not able to resolve the issue after 5 days, so I disabled link protect.  :(
