Getting the error as “Internal error: unable to copy input to source file file_name.crl”
This could be caused by the format of the CRL file, which you are trying to upload. Most of the CAs provides the CRL file in DER format. This should be converted to PEM format before installing in ProxySG.
You can either request the CA to provide the CRL in PEM format or use OPENSSL to convert it to PEM. Use the below command for doing the same
openssl crl -inform DER -outform PEM -in crl.der -out crl.pem
Where “crl.der” is the file received from CA and “crl.pem” is the output in pem format.
