How to avoid this error ?

"'500 Internal Server Error' caused by: x509: cannot validate certificate for xxx.xxx.xxx.xxx because it doesn't contain any IP SANs"

I have crete this router and service in dynamic configuration

http:
routers:
webmin-rtr:
rule: "Host(webmin.{{env "DOMAINNAME"}})"
entryPoints: https
service: webmin-src
tls:
passthrough: true
services:
webmin-src:
loadBalancer:
servers:
- url: "https://xxx.xxx.xxx.xxx:10000"

In my docker-compose file I have setup TLS for all Services using DNS challenge

  - "--entryPoints.https.http.tls.certresolver=dns_challenge_ovh"
  - "--entrypoints.https.http.tls.options=tls-opts@file"
  - "--entryPoints.https.http.tls.domains[0].main=$DOMAINNAME"
  - "--entryPoints.https.http.tls.domains[0].sans=*.$DOMAINNAME"

  - "--certificatesresolvers.dns_challenge_ovh.acme.dnschallenge=true"
  - "--certificatesresolvers.dns_challenge_ovh.acme.dnschallenge.resolvers=$DNS_CHALLENGE_RESOVERS"
  - "--certificatesresolvers.dns_challenge_ovh.acme.dnschallenge.provider=$DNS_CHALLENGE_PROVIDER"
  - "--certificatesresolvers.dns_challenge_ovh.acme.dnschallenge.delayBeforeCheck=$DNS_CHALLENGE_DELAY"
  - "--certificatesresolvers.dns_challenge_ovh.acme.email=$DNS_CHALLENGE_EMAIL"
  - "--certificatesresolvers.dns_challenge_ovh.acme.storage=/acme.json"
