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?
