mutual tls with client certificate [feature request]

[ippocratis]

I have been using owntracks for some time and currently using traccar for serving my device(s) location history I'm looking for a project that will support mutual tls with client certificate authentication on its client I have configured caddy as my reverse proxy with mutual tls so it awaits for a certificate from the client(s) for the sdevice(s) it proxies So server side it is not mantatory to support the feature But it would be great if the client could take advantage from the extra security mtls can provide

Thanks
