Getting 403 Unauthorised on PAR request

[henryallsuch]

We generated our keys before these changes:

https://github.com/oviva-ag/ehealthid-relying-party/pull/86/files

Having updated to the latest docker build and reconfiguring the env files to only pass in sig_jwks.json

We are getting this error back from the PAR request.

{"error":"unauthorized_client","error_description":"client certificate in tls handshake does not match any certificate in entity statement/signed_jwks"}

Do you have any idea how we could fix this? Or what could be causing the issue?
