Traefik V2.2.1 - All services except Traefik service returns [NET :: ERR_CERT_AUTHORITY_INVALID] and uses [TRAEFIK DEFAULT CERT]

Question

I decided to upgrade the version of traefik from 1.7.x to 2.2.1. So I followed the guidelines of the solution above (https://gist.github.com/fatihyildizhan/8f124039a9bd3801f0caf3c01c3601fb) so that traefik in version 2.2.1 would work. Traefik v2.2.1 worked and correctly redirected the http port to https. However, the whoami service redirects from the http port to https but displays the following message:

WHOAMI return

NET :: ERR_CERT_AUTHORITY_INVALID
TRAEFIK DEFAULT CERT

C: \ Windows \ system32> curl https://whoami.ehpop.com.br/
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: http://curl.haxx.se/docs/sslcerts.html
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you would like to turn off curl's verification of the certificate, use
the -k (or --insecure) option.

I would like to know how to resolve this issue. I looked at the traefik documentation but found no errors.

Answer 1

I changed this section

- "traefik.http.routers.whoami.rule=Host(`whoami.ehpop.com.br`, `www.whoami.ehpop.com.br`)"
- "traefik.http.routers.whoami-secure.rule=Host(`whoami.ehpop.com.br`, `www.whoami.ehpop.com.br`)"

for this one

- "traefik.http.routers.whoami.rule=Host(`whoami.ehpop.com.br`)"
- "traefik.http.routers.whoami-secure.rule=Host(`whoami.ehpop.com.br`)"

and it worked!
