I am using Nintex 2013 and when I am trying to do the Nintex Live storage connection test I get a error:
An operation failed because the following certificate has validation errors:
Subject Name: CN=*.blob.core.windows.net
Issuer Name: CN=MSIT Machine Auth CA 2, DC=redmond, DC=corp, DC=microsoft, DC=com
PartialChain: A certificate chain could not be built to a trusted root authority.
RevocationStatusUnknown: The revocation function was unable to check revocation for the certificate.
OfflineRevocation: The revocation function was unable to check revocation because the revocation server was offline.
Take a look at the Appendix B on Nintex Forms Installation guide >>> http://nintexdownload.com/SL/supportfiles/NF2013_installation_guide_english.pdf
Just to follow up with this question for other people looking;
