Relay is giving me errors when trying to simulate an error in sentry

When Im trying to simulate a fail sentry does not log the error can someone help me this is what Im seeing in the relay logs.

Looks like your Sentry instance is down?

Checked with the docker ps -a and the containers are up and can access the sentry url too
but the error keeps showing

{“log”:“2021-01-27T05:06:29Z [relay_server::actors::upstream] ERROR: authentication encountered error: upstream request returned error 503 Service Unavailable\n”,“stream”:“stderr”,“time”:“2021-01-27T05:06:29.797721789Z”}

Had an issue with the firewall now after adding the rule the 503 did not appered any more now is showing the error below regarding authentication

{“log”:“2021-01-27T09:24:46Z [relay_server::actors::upstream] ERROR: authentication encountered error: upstream request returned error 403 Forbidden\n”,“stream”:“stderr”,“time”:“2021-01-27T09:24:46.164584928Z”}

My relay config are as below:

relay:
upstream: “http://10.64.93.21:9000/
host: 0.0.0.0
port: 3000
logging:
level: DEBUG
processing:
enabled: true
kafka_config:
- {name: “bootstrap.servers”, value: “kafka:9092”}
- {name: “message.max.bytes”, value: 50000000} #50MB or bust
redis: redis://redis:6379
geoip_path: “/geoip/GeoLite2-City.mmdb”
http:
_client: “reqwest”

This should just be web:9000. If you put the public IP there (public referring to any IP outside of the private docker compose network), Sentry would require extra authentication via keys which we do not setup in the onpremise installation.
