Multiple n8n instances, BAD GATEWAY on my 2nd n8n

yousername · June 13, 2024, 2:54pm

Running n8n via docker compose

I’m trying to run 2 n8n instances on a single vps with docker-compose.
The first n8n is an older version, 0.9 something. I’d like to run the latest version on a different docker file but using same traefik.
I have 2 separated docker-compose.yml files and in a different folder too.
I can access my old n8n but i can’t access my 2nd n8n named n8n_2024.
It returns Bad Gateway.

I have followed this step

I have made sure that both setup have different labels and ports.

Please help, below are my yml configs
