Hi there,

Trying to run the project locally to contribute to the project, but unfortunately I can not get past the login screen. Using yarn version 4.5.3, node 20.14.0.

Ran yarn workspace proton-calendar start, and then entered Proton account details at localhost:8080/login screen. I'm receiving 200 for /api/core/v4/auth/info, but 422 Unprocessable Content for /api/core/v4/auth:

{
	"Code": 2028,
	"Error": "We are detecting potentially abusive traffic coming from your network and have temporarily blocked logins. If you believe this is in error, please contact us here: https://proton.me/support/appeal-abuse",
	"Details": {}
}

Proxy seems by default to redirect /api,/internal-api -> https://mail.proton.me.

I noticed #419, #343 and #304 also describe issues with getting a local dev environment running, but I'm not seeing any references to this specific problem. (I'm not getting any captchas, for instance).

Also tried re-connecting to other VPN servers, but that did not seem to resolve the issue. Any help would be greatly appreciated!

Start with the local command yarn workspace proton-calendar start and reproduce the login request from localhost:8080/login. Inspect the proxy behavior for /api and /internal-api, along with responses from /api/core/v4/auth/info and /api/core/v4/auth; done means the local development login flow no longer returns the reported 422 error.
