Sentry not logging errors

My relay settings are like these too

relay:
upstream: “http://web: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”

I`m getting this error

{“log”:“2021-01-22T05:54:30Z [relay_server::actors::upstream] ERROR: authentication encountered error: upstream request returned error 503 Service Unavailable\n”,“stream”:“stderr”,“time”:“2021-01-22T05:54:30.828903722Z”}
