We have a customer who are trying to access their site (ex: https://wiki.abc.com) inside corp firewall and received "security certificate error". The same site will be accessible outside of the firewall.
The complete error is below:
"There's a problem with this website's security certification
The security certificate presented by this web site has expired or not yet valid
Security certificate problem may indicate an attempt you fool you or intercept any data you sent to the server
We recommend that you close this web page and do not continue to this website
->click here to close
-> continue to this website(not recommended)"
Can you suggest how we can troubleshoot and fix this issue
