Hi people, Does anyone know about this error? I was investigating and nothing, I did not find anything relevant to solve it. I'm not sending many emails at the same time or anything weird. Any help or something to investigate? Thank you all !!! Below, you will find a part of the code where I involve email sending. (gmail) Thank you ale

P.S. I also commented the lines corresponding to SPIFFS to separate topics and the error remains the same.

include

   EMailSender emailSend("*************@gmail.com", "*****************", "**********@gmail.com", "Nombre", "smtp.gmail.com", 465);
    RECIPIENT_EMAIL = "**quienrecibe****@gmail.com";

    EMailSender::EMailMessage message;
    message.subject = "Curva de horno.";
    message.message = "Adjunto la curva solicitada.";

    envioFile = "quema_2022.11.05_18.37.csv"; 
    Serial.println(envioFile);
    EMailSender::FileDescriptior fileDescriptor[1];
    fileDescriptor[0].filename = (envioFile);
    fileDescriptor[0].url = ("/" + envioFile);
    fileDescriptor[0].storageType = EMailSender::EMAIL_STORAGE_TYPE_SPIFFS;
    fileDescriptor[0].mime = MIME_TEXT_PLAIN;
    fileDescriptor[0].encode64 = true;

    EMailSender::Attachments attachs = {1, fileDescriptor};
    Serial.println(RECIPIENT_EMAIL);
    EMailSender::Response resp = emailSend.send(RECIPIENT_EMAIL, message, attachs);

    Serial.println("Sending status: ");
    Serial.println(resp.status);
    Serial.println(resp.code);
    Serial.println(resp.desc);
