Help accessing proxmox

I am running proxmox on 192.168.1.100, traefik is in a docker container on 192.168.1.234. I want to access proxmox from a subdomain. I have subdomains working with traefik, but only docker containers in the same docker-compose.I tried to install the proxmox cert onto the traefik container. the proxmox route is picking up in the traefik website showing its successful.
but docker traefik logs read 2025-05-13T00:51:17Z ERR 500 Internal Server Error error="tls: failed to verify certificate: x509: certificate signed by unknown authority"
my docker-compose, proxmox.yml, and traefik yaml can be found at

please help!
thank you

As a first step, you can try a global insecureSkipVerify in Traefik static config (doc).

Note that http is not a Traefik static config root element. It belongs in a Traefik dynamic config file, loaded via providers.file in static config.
