I am currently using easypanel which uses traefik in front of docker as my reverse proxy.
How do I correctly set up traefik for to make activity pub work.
Currently getting this
ERROR Could not get webhook secret for ActivityPub FetchError: invalid json response body at https://pupontech.com/.ghost/activitypub/v1/site reason: Unexpected token ‘<’, "<!DOCTYPE "… is not valid JSON

Same problem here.

Same here, I just can’t use Ghost behind Nginx as reverse proxy.
