Error : Can not retrieve server list

[Ciloe]

Hi there, I have an error when using your code. When I launch my command, they are not problem. But sometimes, I have the title error : Can not retrieve server list. Do you know this error ?

My code :

        $io = new SymfonyStyle($input, $output);
        $io->title('Launch Command speedtest');

        $this->manager->beginTransaction();
        try {
            $speedtest = new Speedtest();
            $speedtest->getServers();
            $speedtest->getBestServer();
            $speedtest->download();
            $speedtest->upload();
            $results = $speedtest->results();

            $io->note('Speedtest finish');

            $logger = new Logger();
            $logger->setUpload($results->getUpload())
                ->setDownload($results->getDownload())
                ->setLatency($results->getLatency())
                ->setBytes(['receive' => $results->getBytesReceived(), 'sent' => $results->getBytesSent()])
                ->setLaunchedAt(new DateTimeImmutable())
            ;

            $this->manager->persist($logger);
            $this->manager->flush();

            $this->manager->commit();
            $io->success('Speedtest finish.');

            return Command::SUCCESS;
        } catch (Exception $e) {
            $this->manager->rollback();
            $this->logger->critical($e->getMessage(), ['commandLaunch']);
            $io->error(sprintf('Speedtest error : %s', $e->getMessage()));

            return Command::FAILURE;
        }

Any ideas ? It's appear every two times. I have a cron that launch the command every 15'' and it's failed every 30''. Thanks !

Hi, this sounds like communication error, but I can't be sure without more information
