Hi, I have to maintain system that use traefik and I have to change certificate. When I changed it, I see log from traefik container like this, and my system cannot be accessed anymore :(. Can someone help me to find the problem cause, thank you.
This is the full error message I've got.
Unable to obtain ACME certificate for domains "reverse-proxy.traefik." detected thanks to rule "Host:reverse-proxy.traefik." : cannot obtain certificates: acme: Error 400 - urn:ietf:params:acme:error:rejectedIdentifier - Error creating new order :: Cannot issue for "reverse-proxy.traefik.": Domain name ends in a dot
This is my traefik.toml
