Why are the subroutes from my connect-src CSP rule still being blocked?

Question

I have the following CSP rule on my server:

connect-src 'self'  https://exampleurl.test.pro/

But when a subroute of this url is being called it gets blocked by the CSP rule.

https://exampleurl.test.pro/ppms.php?action_name=example&rec=1&r=018609&h=9&m=21&s=34&url=https%3A%2F%2Fexample.azurewebsites.net%2F&urlref=https%3A%2F%2Flogin.example.com%2F&_id=45a27339c6f79315&_idts=1652252243&_idvc=1&_idn=0&_viewts=1652252243&send_image=1&ts_n=jstc_tm&ts_v=2.6.10&pdf=1&qt=0&realp=0&wma=0&dir=0&fla=0&java=0&gears=0&ag=0&cookie=1&res=2560x1440&gt_ms=747&pv_id=U3B9Xe

I get the following error:

ppms.js:12 Refused to connect to 'https://exampleurl.test.pro/ppms.php?action_name=example&rec=1&r=018609&h=9&m=21&s=34&url=https%3A%2F%2Fexample.azurewebsites.net%2F&urlref=https%3A%2F%2Flogin.example.com%2F&_id=45a27339c6f79315&_idts=1652252243&_idvc=1&_idn=0&_viewts=1652252243&send_image=1&ts_n=jstc_tm&ts_v=2.6.10&pdf=1&qt=0&realp=0&wma=0&dir=0&fla=0&java=0&gears=0&ag=0&cookie=1&res=2560x1440&gt_ms=747&pv_id=U3B9Xe' because it violates the following Content Security Policy directive: "connect-src 'self' https://exampleurl.test.pro/".
