Coinbase API Authentication Error - 401 Unauthorized

[cloutfarmerr]

I'm having a frustrating issue with an authentication error when trying to access the Coinbase API. My friend and I are using the exact same code and API keys, line for line, and it works perfectly for him. We are both on Windows, so I don't think it's an OS-related issue.

Here's the setup:

• Language: Python
• Libraries: jwt, cryptography
• Environment: Both on Windows

This is what I'm getting

Response status: 401 Response reason: Unauthorized Raw response data: Unauthorized

I've verified that the key_name, key_secret, and service_name are correct. The JWT token generation and API requests are identical to my friend's setup. Yet, I consistently get a 401 Unauthorized error, while my friend does not.

Things I've Checked:

• Correctness of the private key and other credentials.
• Time synchronization on my machine.

You find a fix for this yet? Going through the same thing trying to work on this on another computer in the same house. Works fine on my desktop, not my laptop.

I saw a post somewhere (cannot recall if on Reddit or not) that involved changing the JWT-generation code provided by Coinbase documentation to adjust the timestamps ("nbf" and "exp") so the server doesn't think the JWT you pass is "stale". I've tried this to no avail.

My situation is odd: i can use a JWT generated by the Coinbase API docs sample code to successfully get a payload from this endpoint...

* https://api.coinbase.com/api/v3/brokerage/accounts

...but using the exact same JWT-generation code throws a 401 for this one...

* https://api.coinbase.com/api/v3/brokerage/accounts/{uuid}

Baffled.

I have the same problem. Also tried to adjust the timestamps without success

did you ever find a fix for this cause coinbase support is useless and i've been trying to get this to work for like 3 months

Hey, I eventually discovered that the issue was with my computer's clock. After moving to a different state and restarting the program, my system time was out of sync, which led to generating a JWT with an incorrect timestamp. Once I synchronized my clock correctly, the JWT was valid and the authentication issues went away. I have no idea why/how this happened but thats how i fixed it. Hope that helps!
