I have used the openvidu-call angular app as a base to build a customized app for our company. I am not trying to deploy it to the Openvidu server we have in AWS. I have updated my /opt/openvidu/docker-compose.override.yml file with my image (which was generated using the following command: “docker build -f docker/custom.dockerfile -t bridgeinsure/kottervidu --network host --build-arg BASE\_HREF=/ .” After which i run sudo ./openvidu restart which results in no errors. However when i browse to the app it gives me the nginx 502 bad gateway error. I suspect the issue is the http vs https issue mentioned "It’s very important expose your application in port 5442 and use the http protocol”? Since my app automatically goes to https when I browse … [http://vid.keithgallant.com](http://vid.keithgallant.com) Can someone please help explain how i can make this happen? NOTE: I did post this question as a followup to another topic in the “Issues Developing apps” category … i apologize for the repitition but i am under the gun to get a live demo deployed. Everything works perfectly when running locally. Thank you. Keith Gallant ---

A 502 means that the nginx container is not able to reach your OpenVidu Call App. Is your app running over http in port 5442? What the port 5442 means is that your app should be exposed in OpenVIdu at port 5442 so the nginx container can reach it through [http://localhost:5442](http://localhost:5442) Did you try to do a curl request to the app? Something like: ```auto curl localhost:5442 ``` If the App is based in OpenVidu Call, it should return an html. If that does not return something, your app is not running at 5442. ---

cruizba Thank you for your reply. the curl request does fail ( Failed to connect to localhost port 5442: Connection refused) … how do i make that happen? Is that a config change needed inside the angular app? Or within the build command or docker? Keith ---

After the build, did you configured the image in the docker-compose.override.yml? ```auto version: '3.1' services: # -------------------------------------------------------------- # # Change this if your want use your own application. # It's very important expose your application in port 5442 # and use the http protocol. # # Default Application # # Openvidu-Call Version: 2.19.0 # # -------------------------------------------------------------- app: image: bridgeinsure/kottervidu <--------- THIS restart: on-failure network_mode: host environment: - SERVER_PORT=5442 - OPENVIDU_URL=http://localhost:5443 - OPENVIDU_SECRET=${OPENVIDU_SECRET} - CALL_OPENVIDU_CERTTYPE=${CERTIFICATE_TYPE} logging: options: max-size: "${DOCKER_LOGS_MAX_SIZE:-100M}" ``` After that, execute `./openvidu restart` ---

Yes I did do that. And there are no errors showing after that restart. ---

When I look at the entrypoint.sh file in my app it has the following: cd /opt/openvidu-call nodemon openvidu-call-server.js however this doesnt exist on my AWS server? Is this something generated inside the docker? And should the folder be my new image name? ie kottervidu ---

Did you modified something of the Dockerfile `custom.dockerfile` or the `entrypoint.sh`? You can forget about the docker image if you want. Instead of building the Docker container, just clone your project into the server and run it at port 5442 with http. So if you’re able to run your app at port 5442, you can do that in the server. ---

I ddnt edit the custom.dockerfile or entrypoint.sh file no … To “run it at port 5442 with http” do you mean run the docker run command from within the AWS server? If doing this … i will have to go to [http://vid.keithgallant.com:5442](http://vid.keithgallant.com:5442) in order to use the app though right? ---

- No, I was talking about running the node server directly in the machine using port 5442. - No, you don’t need to access through 5442. Anything running at port 5442 will be redirected to 443 by the nginx proxy
