Can you perhaps try the following and see if it gives you any better results from within bash or list the specific version of F5 you are running as this was put together against v13.1.5.
# set directory path to location of certs (change to custom partition if not stored in /Common)
cd /config/filestore/files_d/Common_d/certificate_d
# obtain the full name of cert + ca bundle
ls
# test OCSP response using openssl
# -issuer & -CAfile are both using a cert bundle containing both the Intermediate + Root CA for DigiCert
openssl ocsp -no_nonce -header Host ocsp.digicert.com -issuer \:Common\:digicert_bundle.crt_198653_1 -cert \:Common\:your.website.com.crt_234232_1 -url http://ocsp.digicert.com -CAfile \:Common\:digicert_bundle.crt_198653_1
