The request was not processed and can be safely retried

[RoodFruit]

Hi,

All of a sudden we're receiving the error "The request was not processed and can be safely retried.". Until now, everything worked perfectly.

Anybody got an idea of what the error means?

Info

• Php 8.1.10
• Apache/2.4.54
• OpenSSL 1.1.1s

Code:

\Amp\Loop::run(
    function () {
        $handshake = new \Amp\Websocket\Client\Handshake('wss://...');

        while (true) {
            try {
                $connection = yield connect($handshake);

                yield $connection->send(json_encode([...subscription_info...]));

                while ($message = yield $connection->receive()) {
                    // ...
                }
            } catch (Exception $e) {
                // ...
            }
        }
    }
);

Based on the exception stack containing a TlsException there may be an error with the server you're connecting to. Use UnprocessedRequestException::getPrevious() to get the previous exception.
