[solved] Remote error: tls: bad certificate" with traefik 2.3.5

Hello all,

I'm unfortunately still a complete newbie when it comes to Traefik and have gained my knowledge purely from various forums. Currently I'm running Traefik 2.3.5 under Docker. When I call it via its FQDN URL, the page is displayed cleanly and the Let's Encrypt certificate is also pulled cleanly.

Now I wanted to continue with Bitwarden_RS. But here Traefik apparently does not issue me a certificate at Let's Encrypt.

The following message is generated in traefik.log

time="2020-12-15T16:16:40Z" level=debug msg="Serving default certificate for request: \"bw.fqdn.tld\""
time="2020-12-15T16:16:40Z" level=debug msg="http: TLS handshake error from *.*.*.*:17376: remote error: tls: bad certificate"

Am a little helpless right now. What other information do you need to help me?

kind regards H-BLOGX
