Can't Sign PDF using USB token epass2003 with C# iTextsharp 5.4.0 code . But when using Java itextsharp 5.5.8 i am able to sign the PDF

Question

Hi I am not able to sign the PDF using C# itextsharp 5.4.0 library

Following are the logs generated in Java Code which works fine:

NOTE: The java code works fine.

But the C# itextSharp code doesn't work . It is hitting the wrong URL which doesn't exist.

UrlList:
"_https://www.ncodesolutions.com/repository/ncodeca14.crl"
"_http://cca.gov.in/rw/resources/CCAIndia2014Latest.crl"

Retrieves the OCSP URL from the given certificate as.

"https://www.ncodesolutions.com/repository/ncodeca.cer"

Which is different from the url's present in the above urlist and from java.

Exception:The remote server returned an error: (404) Not Found.

Please Provide Help or solution for the same.

NOTE: _ is added before every link so that i could post my question.

Thanks
