Different Behavior On LAN vs. WAN

I have need to host several tiddlywikis. I do this on my own website via subdomains and proxying to locally (on my LAN) hosted wikis. The behavior on the LAN does not match behavior on my WAN. No wiki has a “+” button to create a new tiddler when connecting via local IP and I can not save any changes, but they work fine when accessing through my Nginx server proxy on the WAN.

My normal process for creating a new wiki is:

0 - Start from user’s home directory

  1. tiddlywiki [NEW_WIKI_NAME] --init server
  2. Edit my start_tiddlywiki.sh and stop_tiddlywiki.sh scripts which include: screen -S tiddly-[NEW_WIKI_NAME] -dm tiddlywiki [NEW_WIKI_NAME] --listen host=[LOCAL_MACHINE_IP] port=[PORT]"readers=(anon)" writers=[USER] username=[USER] password=[PASS]
  3. Test to ensure wiki works locally
  4. Edit my sites-enabled/[DOMAIN] to add the proxy on a subdomain
