Routes Error after upgrade to v4.5.5

Hi,
I have just upgraded to v4.5.5 and I am now getting errors I have never received before.

Code:

CRITICAL - 2024-09-17 14:15:42 --> GuzzleHttp\Exception\ConnectException: cURL error 6: getaddrinfo() thread failed to start (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://identity.xero.com/connect/token
[Method: POST, Route: quote_hook]

During the upgrade I noticed Config/Routes had been changed and Config/Routing had been added. As part of the upgrade I ensured by previous Routes settings ($routes->setDefaultNamespace('App\Controllers');$routes->setDefaultController('Home');$routes->setDefaultMethod('index');$routes->setTranslateURIDashes(false); $routes->set404Override(); were replicated in Routing.
Any assistance would be helpful?

CI4 does not use Guzzle.

CI4 does not use Guzzle.

Thank you. 
However, my application that is implemented on the CI4 framework uses Guzzle, and it looks like it's having problems finding a route (Routes are in CI4).
If it's not a problem with routing I will looks elsewhere.

1. CI4 does not use Guzzle at all.
2. The error is clearly caused by Guzzle.

Why do you think it's having problems finding a route in CI4?

When you upgrade CI4, you must read the upgrading guides:
https://www.codeigniter.com/user_guide/i...ading.html
Did you read them, and followed the  instructions?

Reading the Guzzle doc's, he needs Guzzle v7 for PHP 8+.

What did you Try? What did you Get? What did you Expect?
