Unable to execute check for https://xxxx.com/config/config.php

We have matomo version 4.10.1 running on our server. When I logged in to check the status of the platform, I found a few issues termed as warnings and all of them are throwing the same error. “Unable to execute check for https://xxxx.com/xxx/xxx.php”.
How could I resolve the error?

In which section do you see this warning?
