Is anyone #SelfHosting a #Friendica install on a #RaspberryPi ?

I'm delving into self-hosting on my own equipment for the first time, and I've got a problem that's most likely somewhere in Friendica itself rather than a self-hosting problem.

I have a Friendica install running, it can message other fedi accounts, but it doesn't fetch posts. Also, despite Friendica acct showing me as following my mastodon acct (as mutual), my mastodon account doesn't show the friendica acct as a follower, but it does show up in the list that the mastodon account is following.
