Question

Hey folks I feel like I ve missed something obvious but how do I configure Prefect 2 x to run successfully behind a reverse proxy I see references to `PREFECT SERVER BASE URL` but that seems to be for v1 I m using Traefik to reverse proxy https traffic to Prefect The UI loads but I see this error displayed Can t connect to Orion API at <http 0 0 0 0 4200 api>

```root e6695489d725 opt app prefect prefect config view PREFECT PROFILE= default PREFECT ORION API HOST= 0 0 0 0 from env PREFECT ORION DATABASE CONNECTION URL= from env ``` My interpretation was that specifying `0 0 0 0` for the PREFECT ORION API HOST was instructing Prefect to listen on non localhost but maybe that was a misunderstanding

Ok answering my own question it seems that the `PREFECT API URL` needs to also be set for the server when the server is running behind a reverse proxy Here was my fix ```$ nomad alloc exec i t task prefect server 58c8ec49 bin bash root 11499a2af292 opt app prefect prefect config view PREFECT PROFILE= default PREFECT API URL= <https prefect orion dev mycompany tld api> from env PREFECT ORION API HOST= 0 0 0 0 from env PREFECT ORION DATABASE CONNECTION URL= from env ```
