Запускаю traefik с пример из документации. Не работает tls:

time="2020-06-23T21:54:24Z" level=error msg="failed to load X509 key pair: tls: failed to find any PEM data in certificate input"
time="2020-06-23T21:54:24Z" level=error msg="Unable to add a certificate to the entryPoint \"https\" : unable to generate TLS certificate : tls: failed to find any PEM data in certificate input"
time="2020-06-23T21:54:25Z" level=error msg="failed to load X509 key pair: tls: failed to find any PEM data in certificate input"
