Dear fellow or potential fellow gotosocial instance admins,I've come up with a novel way to set up a #gotosocial server behind a reverse proxy, which avoids the use of making new firewalling rules - both on a VPS, and creating port forwarding on one's home router. This method is ideal for minimizing the cost of running one's own #ActivityPub/#Mastodon server, in a way that leverages inexpensive fast storage on the backend (say, on a #RaspberryPi 5, 2GB of RAM, with an NVMe). As many valiant and praiseworthy Mastodon server admins might attest to, renting cloud VPS' can cost a lot, especially when storing many tens or hundreds of GB of user data.
