NewConnectionError(’<urllib3.connection.VerifiedHTTPSConnection object at 0x7faa07018390>: Failed to establish a new connection: [Errno 111] Connection refused’,)**

I have our web proxy configured in ~redash/.docker/config.json

Redash server container env doesnt have a proxy variable set, as reported with “docker exec containerid bash -c ‘env’”

Any ideas?

Ah ok, simple soultion. Edit /opt/redash/docker-compose.yml.
Add to the environment section, for example,
http_proxy=http://proxy:8080
https_proxy=http://proxy:8080
Then restart containers and do a quick test showing the variables are set, example,
docker ps docker exec 21497c97dce8 bash -c ‘env’ | grep -i proxy
Then back to redash new query with JSON data source.
