Hey @takeshi0405.expo.dev,

Where you eventually able to log in? If not, could you try logging in via expo.io to see if that works?

Cheers,
Adam

thanks for your response.
I cannot log in by commandprompt and powershell, but can log in expo.io by browser(google chrome).

using ‘expo start’ and enter ‘u’,
when I am asked for my email address, I type ‘a’ , android start…

I use a proxy in the network. Is this the cause?

I’m using this version so I don’t have WSL installed.

Hi,
When I tried this command, no error occurred.
May not be due to proxy settings…

Invoke-RestMethod -Uri https://exp.host/--/api/v2/auth/loginAsync -Method Post -body "username=username&password=password"
