What I have tried:

CmsSigner signer = new CmsSigner(certificate);

signer.DigestAlgorithm = new Oid("SHA256");// ("2.16.840.1.101.3.4.2.1");
signer.SignedAttributes.Add(new Pkcs9SigningTime());
// create the signature
signer.IncludeOption = X509IncludeOption.None;

signedCms.ComputeSignature(signer, false);

"Internal server error" is just a message telling you that something went wrong; you'll need to track down the real error to find out what the problem is.

Assuming this is ASP.NET, there should be an entry in the application event log with more details. Alternatively, use Failed Request Tracing[^] to trace the failed request.

It's exploding probably because "SHA256" is not proper Oid descriptor.

It should be:
signer.DigestAlgorithm = new Oid("2.16.840.1.101.3.4.2.1");


An "Internal server error" means that you haven't properly setup the objects and/or properties required to use the Signer. There's probably more that's wrong but you're not showing enough code to make that determination.
