I came across this problem today (13/07/2015) when going to the ATO tax portal using Oracle Java 1.7.0 on Firefox 38 & 39
: Secure Connection Failed
:
: An error occurred during a connection to
authentication.business.gov.au. Invalid OCSP signing certificate in OCSP response. (Error code: sec_error_ocsp_invalid_signing_cert)
:
: 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.
Looks like the problem is at the ATO's end, as a temp work around I've disabled ocsp_tapling
Within the users firefox
1. Go to about:config
2. set 'security.ssl.enable_ocsp_stapling' to false
3. Try the
bp.ato.gov.au website again
Warning: This does lessen your security so make sure you change it back to true as soon as you can. Hopefully the ATO fixes this problem soon.
