C_GetOperationState Error when performing mTLS with s_server

[WolfDan]

Hey!

I'm trying to check an mtls connection with s_server, s_client, and the PKCS11 provider, but the s_server throws a C_GetOperationState error when the client is trying to do a post handshake new session; here's an image of the process and the error

Where the s_server uses an intermediate EC prime256v1 private key from PKCS11 and s_client uses an end entity private key from pkcs11 (the end entity was signed by the intermediate)

I've seen the C_GetOperationState error many times, but this is the first time this actually crashed something, so here's the debug log of s_server using the -debug flag

Regarding the driver I'm using is tpm2-pkcs11 library

I'm unsure what's the root of the issue at all, any idea what it might be?

Thank you!

Images of text are not very useful ... can you please set PKC11_PROVIDER_DEBUG and get a debug file?
C_GetOperationState is generally optional, so I am surprised as well and need more info.
