Problem getting datum gateway running on start9 with Bitcoin knots

Hey I’m trying to run datum, and have defaults on knots and datum, and I did the auto config that datum requested of knots. it tries running and then stops and the logs of datum show this error.
Knots and electrum and mempool all work fine.
Error log on datum gateway
2026-01-24T06:56:02+08:00 Error: The blocknotify field is null or not set in Bitcoin’s configuration. Your Start9 Bitcoin package may not support adding this. Knots is required.

Do you actually have Knots installed? This is the error you get when you try to use the Datum with Core and try to autoconfig.

In any case, if you go to Config you can add the required field.

curl -s -m5 http://datum.embassy:7152/NOTIFY

Yes it is knots, and that has been added into blocknotify, that is why im confused by the error.

Mine did this as well on the initial attempt to run DATUM, was resolved simply by restarting Knots and then DATUM.

Hi All, the issue has been resolved

I believe it was an issue with my router settings. Once i updated them i uninstalled datum, restarted knots and resaved the blocknotify address

I then reinstalled datum, inserted my wallet address. Then started the process. Then worked
