    Tengo un servidor de hosting en un VPS, de un momento a otro dejó de funcionar el tráfico por el puerto 80 y 443, lo que significa que las webs que están hospedadas en mi servidor no se ven. Un dato curioso es que si reinicio el servidor, luego de iniciar por unos pocos minutos sí se puede acceder a las páginas web, pareciera que después que inicia el servidor hay algo bloqueando las peticiones. Necesito alguien que me solucione el problema.

    Cuando reinicie el servidor contratado en Digital Ocean, los correos dejaron de funcionar y no puedo acceder a mi cuenta porque me pide mi correo que esta caído por el reinicio que hice en Digital Ocean. Por lo tanto necesito volver a acceder a mi cuenta para reiniciar nuevamente y colocar otra dirección de correo que no sea la misma que tengo en el servidor

    Hello, I have a new Smartermail email server loaded on Windows standard 2019. I'm unable to get SSL/TLS secure connections to work on ports 993, 465, and 587 to work. I've installed SSLs and made sure the ports are open, however, when you reboot the server the ports then show closed even though in Windows defender the rules still show the ports open. This project requires Smartermail experience and is marked urgent!

    We have WonderPush push notifications installed on our magento 2 website - however subscribers are not being shown in the dashboard. A check of Console shows a number of errors relating to "content security policy directive" which frankly means nothing to me! Troubleshooting document from WonderPush is of no use to me but may help someone who knows what they are looking at! We need someone to fix this for us and explain what happened as we followed all instructions from WonderPush seems to offer advice on this but again, its beyond my expertise.
