eRS endpoint certificate

hi,

appreciate your help on this,
recently got the certificate from NHS for eRs INT endpoint and it seems not working and getting the following error
javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Untrusted Server Certificate Chain.

I have added the newly available rootca and subca into truststore as well

any thoughts?
thanks

The notes on this page shows what I did to get a spine certificate working

I may have the code for access the token from the smart card if you need that?

p.s. I knew it took around a week to get this all working, the API is pretty straight forward once you’ve got past all the tokens.
