I had no problem with the link. There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own. https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message [https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors?redirectlocale=en-US&redirectslug=Error+loading+web+sites Websites don't load - troubleshoot and fix error messages] http://kb.mozillazine.org/Error_loading_websites [https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean What do the security warning codes mean]

If I try https://www.esic.in/ I get this when I click the Advanced button on the error page: Error code: SEC_ERROR_UNKNOWN_ISSUER When I put it into this test site: https://www.ssllabs.com/ssltest/analyze.html?d=www.esic.in&latest The report indicates there is an incomplete certificate chain, meaning the site certificate cannot be tracked back to a root certificate trusted by Firefox. This is why Firefox considers it to have an "unknown issuer."

We regularly see issues reported with the esic website. Even with the correct root certificate installed this website doesn't work. *http://www.cca.gov.in/cca/?q=root_certificate.html *[/questions/1250565] hello sir, I am from nasik and i am trying to log in esic site for my work from last 3 to 4 days but i found the same problem that "connection failed" for esic.
