Start by adding my Umbrel app store if you haven’t already, and then install Knots (BLAKE2b) Companion. Let it complete the IBD (Datum Gateway won’t work until it does).
Once that is done (probably a day or so), let me know and I’ll give you a link to a special version of Datum (BLAKE2b) Companion that you can test (assuming that I can fix the problem in Datum Gateway without requiring the ASIC to be patched).
