I recommend setting up a home server using any old PC or laptop you have. Not having a static public IP may not be an issue, but if you are behind CGNAT, and cannot forward ports, you can route your data through a free provider like Oracle or Google. Those free servers are very weak but will be good enough to just pass through the data. This way even if they randomly decide to shut down and delete your instance, your data stays intact. I also recommend using SSL/TLS pass through, instead of termination, for better privacy.
