@miles after restoring the secret file, you have to start gossipping with peers to resync the database.
Either:

1. Have another peer on the LAN who follows you (maybe)
2. Manually make a gossip connection. e.g.:
   sbot gossip.connect 'net:ssb.celehner.com:8008~shs:5XaVcAJ5DklwuuIkjGz4lwm2rOnMHHovhNg7BFFnyJ8='
3. Restore your old ~/.ssb/gossip.json file, or get one from someone else. Then restart ssb-server

"RangeError: Maximum call stack size exceeded"

I have frequently run into that error message, so for months I have been starting sbot (I'm not on ssb-server yet) with

  node --stack-size=51200 ~/.npm-global/bin/sbot server

(For some reason, node doesn't accept values greater than 51200.)

This this has already been answered but here is some more
