Hello & happy new year!

you did not mention, how you generate "".

nginx stapling support may work in two operational modes:

1. only "ssl_stapling on" and no "ssl_stapling_file" given.
-> upon the first request nginx will fetch OCSP sapling data from CA's OCSP-Server and send this information as part of the second any any following requests

2. "ssl_stapling on" and "ssl_stapling_file" given.
-> you have to manually provide OCSP data. nginx will server any request including these OCSP data.

The file you reference as "ssl_stapling_file" could be generated by this command:

$ openssl ocsp -no_nonce -respout "${OCSP_STAPLING_FILE}" -CAfile "${CA_CHAIN}" -issuer "${ISSUER}" -cert "${CERT}" -url "${OCSP_URI}"
$ kill -HUP $( cat /path/to/ )

that has to be done again after some days.
