Are RSA sha512 message digest Server Certificates Valid?

[mayakerostasia]

I have a certificate authority which uses sha512 for the default message digest.

Can I use this CA with rocket to sign the TLS certs and use mutual TLS

I'm running into this error when trying to communicate with these certs
Warning: tls handshake with 10.0.0.201:51226 failed: invalid peer certificate contents: invalid peer certificate: UnsupportedCertVersion

I'm wondering if that's the issue or if it's a configuration problem.

I'm sorry if there's not enough info here, I'm not sure what would all be useful to share to help debug this issue.

The server is very similar to the TLS example in the examples at the moment except for I'm using my own CA in stead of the self signed certs.

Here's my Rocket.toml file

[default]
address = "0.0.0.0"

[default.tls]
certs = "private/rustfs/rustfs.pem"
key = "private/rustfs.key"

[default.tls.mutual]
ca_certs = "private/ca_cert.pem"
mandatory = true
