Error in Caddy Log, breaks reverse proxy.

[Obsidiannite21]

Hello. I'm getting the following error in my Caddy Log:

WRN ts=1689260875.3299775 logger=http.matchers.maxmind_geolocation msg=cannot lookup IP address address=192.168.0.1:43852 error=invalid node in search tree

Caddy works for a random period of days then this error will flood my log. It will persist & repeat until I reboot Caddy and I can't access the items behind the reverse proxy unless I am on the local network. I pull the database once a day using cron / script, but other than that it's a pretty standard config. Any suggestions?
