docker container has no access to localhost webhook - docker

Question

I'm working on our webhook locally before building a docker container, and want my (Linux) container to communicate with it, using host.docker.internal:ping.
It had been working before, but lately, for some reason, I'm getting this error from our graphql-engine, Hasura:
{
"timestamp":"2019-11-05T18:45:32.860+0000",
"level":"error",
"type":"webhook-log",
"detail":{
"response":null,
"url":"http://host.docker.internal:3000/simple/webhook",
"method":"GET",
"http_error":{
"type":"http_exception",
"message":"ConnectionFailure Network.Socket.getAddrInfo (called with preferred socket type/protocol: AddrInfo {addrFlags = [AI_ADDRCONFIG], addrFamily = AF_UNSPEC, addrSocketType = Stream, addrProtocol = 0, addrAddress = <assumed to be undefined>, addrCanonName = <assumed to be undefined>}, host name: Just \"host.docker.internal\", service name: Just \"3000\"): does not exist (Temporary failure in name resolution)"
},
"status_code":null
}
}
Here's my docker compose:
version: '3.6'
services:
postgres:
image: postgres:11.2
restart: always
ports:
- 5432:5432
volumes:
- postgres:/var/lib/postgresql/data
environment:
- POSTGRES_DB=postgres
- POSTGRES_USER=...
- POSTGRES_PASSWORD=...
graphql-engine:
image: hasura/graphql-engine:latest
depends_on:
- postgres
restart: always
environment:
- HASURA_GRAPHQL_DATABASE_URL=postgres://...:...#postgres:5432/postgres
- HASURA_GRAPHQL_ACCESS_KEY=...
- HASURA_GRAPHQL_AUTH_HOOK=http://host.docker.internal:3000/simple/webhook
command:
- graphql-engine
- serve
- --enable-console
ports:
- 8080:8080
volumes:
postgres:

The local project is for sure working and listening to port 3000. Nontheless, it isn't receiving any requests [as it should] from the graphql-engine container. Could it be related to our proxy?

Answer 1

Seemed to be an issue with Docker Desktop.
Uninstalled the whole docker environment and rebuilt it all, that fixed it.
