Question: I am working on a nodejs twitter api and it's working perfectly fine in the local env but when I try to containerize, it fails with a 401 error from twitter.js which is "HTTP 401 Unauthorized client error status response code".

Error

```
> node app.js

Error: Status Code: 401

I did my search on this where I found that this could a time mismatch issue in the docker container. My docker container is running 1 and a half hours behind the actual time. I am not sure if this is the only issue.

My docker file

```
FROM node:13.13.0-alpine

# Create app directory
WORKDIR /usr/src/app

COPY package*.json ./

# Bundle app source
COPY . .

ENV KAFKA_HOST=localhost:9092 \
    KAFKA_TOPIC=tweetstream 

CMD ["npm", "start"]

```

How can I set the right time in this docker image?

Answer: 
For me I need to set the bundler location in my app from "localhost:8081" to "192.168.1.XX:8081" which is my computer's local IP address where Metro bundler runs on and the port is 8081.

If you don't know which port your bundler runs on you can specify it as a parameter like:

```
npx react-native start --port 8081

```

Then you need to specify the location in your development app. To do that:

* Shake your device
* Click change bundle location (I am on RN 0.64 it may differ in yours)
* Give the bundler location of your computer's IP and port where Metro bundler runs on like:

and they started to communicate with each other.
```
yarn start web

```

you can use this command to scan the QR code and see the app in you EXPO app at you mobile
