eRS endpoint certificate


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 Untrusted Server Certificate Chain.

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

any thoughts?

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.
