I found in other projects that people ran into issues when updating the docker version.
What I tried so far:
1. I updated the OS to 24.04.3 Noble
2. Followed the advice to downgrade my docker versions

I think this must be docker related so I am going to close referencing the links from @ThaiJamesLee and https://www.reddit.com/r/debian/comments/1orq9pd/docker_ports_broken_after_debian_12_13_upgrade_on/. If this turns out to be a pangolin issue we can reopen!
@oschwartz10612 Not sure if this should be mentioned somewhere if someone updates their docker engine to 29 and encounters this issue.

For all those who will stumble across this issue, I updated traefik to 3.6.4 and I can access the dashboard again.
I found the solution on this post: https://www.reddit.com/r/selfhosted/comments/1ovz0tt/psa_if_you_update_to_docker_29_and_your_traefik/
