Yes

What was the Problem?

I have audiobookservice service with traefik working perfectly with the resolvers of letsencrypt to test the app for my homeserver and works perfectly but the moment I use my self-signed certificates the app throws an error

"failed to contact server read error ssl=0xb400006f24c6b958: Failure in ssl onessl internal:tlsv1_alert"

The web service with my CA certificates works great but not in the mobile app.

When ussing this certificate request from the traefik tls

in tls.yml of traefik config
tls:
certificates:
....
options:
internal:
clientAuth:
caFiles: "-----------"
clientAuthType: RequireAndVerifyClientCert
public:
minVersion: VersionTLS12

works with clientAuthType: RequestClientCert - Asks for a certificate but proceeds anyway if none is provided.

but should work with clientAuthType: RequireAndVerifyClientCert - Requires a certificate, which must be signed by a CA listed in clientAuth.caFiles or in clientAuth.secretNames

options from the traefik docs
https://doc.traefik.io/traefik/reference/routing-configuration/http/tls/tls-options/

Steps to Reproduce the Issue

The error throws when is trying to connect to a domain with a self signed certificate.

What was Expected?

Expected to accept and verify a certificate if the connection expects or needs one, because currenlty i think your app expects the connection to dont have a client certificate.
