FetchError: request to https://api.expo.dev/v2/sdks/50.0.0/native-modules failed, reason: unable to verify the first certificate about expo

What solved the problem for me was this: npm/cli#7394 (comment)
I am using the same antivirus and disabling HTTPS traffic scanning has also worked for me.

npx expo start --dev-client works fine for me. It looks like it's a problem with the npm, this if from npm install.

Somehow it works flawlessly on MacBook. Both computers are connected to the same network.

Hey all! I can confirm that nothing has changed on our end related to the SSL infrastructure. If you run into this, it could mean a couple of things, including:

1. You are using a proxy that doesn't properly inherit the SSL chain (see comment)
2. Your ISP is adding a proxy / man in the middle that doesn't follow the proper SSL chain.
3. Node (mostly on Windows) is doing something wrong with the SSL CA certificates.

There are a few Stack Overflow threads that might help (this, that, this one)

You can validate that your ISP isn't doing something weird, or you have a computer-wide proxy, by going to https://api.expo.dev, which should respond with just OK. In your browser, you can verify the certificate information.

Certificate information

Hope this helps! I'll close this issue as it's not actionable on our end.
