Getting a blank page when trying to login with mitm reverse proxy running

[Myles1]

Thank you so much for making this project public. That's super nice of you!

I'm running into an issue while following the instructions here: https://github.com/joshuataylor/snowflake-notes/blob/main/reverse_engineering_tips.md#inspecting-your-http-requests

I ran mitmweb --mode reverse:https://my_account.snowflakecomputing.com --listen-port 8083
Then navigated to http://localhost:8083
Entered the login info, then it loads a blank page and hangs indefinitely.

Do you have any tips for what I might be doing wrong here?
Thanks in advance!

Glad you found it interesting, and sorry for the slow reply.

So there are three subdomains that Snowflake now uses:

1. ACCOUNT.REGION.snowflakecomputing.com
   Used by the "official" drivers.

2. app.snowflake.com
   Used to validate your account identifier, get the region, etc.

3. apps-api.c1.REGION.aws.app.snowflake.com
   Used for API requests

The reverse API instructions made sense when there was a single domain, but the best approach now is to instead use mitmproxy/similar tool then use HTTP_PROXY in either your browser or as an environment variable.

Most HTTP frameworks pick this up out of the box, and should work.

I'm not sure that I follow. Would you be able to give a working example in the same way that you did in the reverse API instructions?
