What are the steps to migrate to accessControlAllowOriginList?

Hi @Akruidenberg,

you just have to change from accessControlAllowOrigin to accessControlAllowOriginList in your TOML or YAML file as per Traefik 2 Documentation.

Even if you have only one entry (domain) remember to use the list format (in YAML is with - and in TOML is with []).
