After hours of trying I have to get help for my issue. I am trying to get OCSP stapling to work with my setup, but am not successful in doing so.
Here is my nginx configuration, without any non-relevant bits.

}
}
I am getting an error in the log files:
2019/04/30 21:28:07 [error] 28718#100839: OCSP_basic_verify() failed (SSL: error:27FFF076:OCSP routines:CRYPTO_internal:signer certificate not found) while requesting certificate status, responder: ocsp.int-x3.letsencrypt.org, peer: 2.16.100.83:80, certificate: "/usr/local/etc/nginx/fullchain.pem"
No matter what I try to include in the file given to ssl_trusted_certificate, I could not fix this. I tried including the full chain, adding the root CA to it, only the CA, only the intermediary.
Adding the root CA into the fullchain.pem file given to ssl_certificate results in errors on SSL verification websites.
Despite all of that, I am still prompted by a OCSP Stapling not enabled. on https://ssldecoder.org and OCSP response: no response sent when using openssl s_client
Any help would be appreciated. I am using let's encrypt.
