How to handle Fatal error: cURL error 7: Failed to connect to xxxx port 443

问题

I have a script that connects to a third party API. It is and should be running on a non-stop loop 24/7 (I use a sleep at the end before restarting the loop).

The problem is that sometimes the third party API gets ddosed or the connection simply drops with this error:

Fatal error: Uncaught exception 'GuzzleHttp\Ring\Exception\ConnectException' with message 'cURL error 7: Failed to connect to xxx.com port 443

Is there any way to "break" on this fatal error to ensure the code is restarted and proceed if the action can be made or must I manually restart each time I get this error?

From Michael's comment

it looks like you can just catch the GuzzleHttp\Ring\Exception\ConnectException exception

like this:

use GuzzleHttp\Ring\Exception\ConnectException;

try {
    // the code which throws the error
} catch( ConnectException $ex ) {
    switch ( $ex->getMessage() ) {
        case '7': // to be verified
            // handle your exception in the way you want,
            // maybe with a graceful fallback
            break;
    }
}

it appears guzzle's ConnectException extends some classes and ultimately extends php's Exception so you can safely use the getCode() method, allowing you to catch an identifier on which you can react accordingly to your needs.
