Hello, I installed typesense in AWS EC2 instance.. curl localhost:8108/health >> returned {ok:true}. My next step is running the docsearch crawler..

Below is my env file
TYPESENSE_API_KEY=xyz
TYPESENSE_HOST=host.docker.internal
TYPESENSE_PORT=8108
TYPESENSE_PROTOCOL=http

Below is the error I am getting while running docker run command

Jason As suggested in this thread https://github.com/typesense/typesense/issues/668, I added inbound/outbound rules to allow port8108 with 0.0.0.0/0 but issue is not resolved..

So you are running Typesense in a EC2 with Docker? Or are you only running docsearch in Docker?

Typesnese is already installed and running in EC2. I want to run scraping job by running below command in EC2.

$ docker run -it --env-file=/path/to/your/.env -e "CONFIG=$(cat config.json | jq -r tostring)" typesense/docsearch-scraper:0.6.0

Try adding --network="host" like this

docker run -it --env-file=/path/to/your/.env -e "CONFIG=$(cat config.json | jq -r tostring)" --network="host" typesense/docsearch-scraper:0.6.0

Could you try adding this docker flag: https://stackoverflow.com/a/62431165/123545

(and remove --network="host" if you’re using the flag above)
