```
my setup is based on
[Ultimate Traefik Docker Compose Guide [2022] with LetsEncrypt | SHB](https://www.smarthomebeginner.com/traefik-docker-compose-guide-2022/) I used the same docker compose on my local machine and it setup fine.
docker-compose: [docker-compose treafik - Pastebin.com](https://pastebin.com/AxVZjZdy) (edited)

When you [search the Internet](https://www.google.com/search?q=tls+%22bad+record+mac%22), it seems that this is often blamed on faulty hardware, software or network connection.
I would try to spin up a new node with fresh install and newly downloaded certs (if you use paid ones).

Thanks for the reply! If you mean start a new server by spinning a new node, that is not really a possibility. I am using the swag container from linuxserver for years on this machine and have never had a issue with getting a new cert or renewing one.

Was it a single error, just a flipped bit during a connection, or is it happen regularly?

It just keeps repeating as soon as a spin up the container.

I had this error occur when I created a docker container using traefik router/service names already in use by another container (i.e. lazy compose copy/paste)
Check this before replacing your network infrastructure 😉
