Hi again,
I manually installed the gateway, dashboard and pump and everything is working. The dashboard code in the all-in-one docker version must not be up to date or something else is missing…
NB : after assembling info from the tyk’s old docs and the current one, I finally understood that a reverse proxy has to be manually setup to map :80/ to :3000/{ORGID}/portal … It may be relevant to add it to the getting started :).
