Eth Node inaccessible - Githubissues

For those who come along, I ran into this issue after firing up the GKE environment and noticing my Pods were going through CrashLoopBackOff. I was getting a 502 from the targeted Eth Node in chainlink-node.tf

Validated with wscat:

devadmin@ThunderCloud:/mnt/e/Development/chainlink-gcp$ wscat -c wss://ropsten-rpc.linkpool.io/ws
error: Unexpected server response: 502

Setup my own Eth Node on Infura and validated it connects properly:

> devadmin@ThunderCloud:/mnt/e/Development/chainlink-gcp$ wscat -c wss://ropsten.infura.io/ws/v3/a13a37a22d784e39926def7c35e9e415
Connected (press CTRL+C to quit)

Then I modified the chainlink-node.tf with my changes;

resource "kubernetes_config_map" "chainlink-env" {
  metadata {
    name      = "chainlink-env"
    namespace = "chainlink"
  }

  resource "kubernetes_config_map" "chainlink-env" {
  metadata {
    name      = "chainlink-env"
    namespace = "chainlink"
  }

  data = {
    #"env" = file("config/.env")
    ROOT = "/chainlink"
    LOG_LEVEL = "debug"
    ETH_CHAIN_ID = 3
    MIN_OUTGOING_CONFIRMATIONS = 2
    LINK_CONTRACT_ADDRESS = "0x20fe562d797a42dcb3399062ae9546cd06f63280"
    CHAINLINK_TLS_PORT = 0
    SECURE_COOKIES = false
    GAS_UPDATER_ENABLED = true
    ALLOW_ORIGINS = "*"
    DATABASE_URL = format("postgresql://%s:%s@postgres:5432/chainlink?sslmode=disable",var.postgres_username,random_password.postgres-password.result)

    ETH_URL = "wss://ropsten.infura.io/ws/v3/a13a37a22d784e39926def7c35e9e415"
  }
}
