New tubeless setup: losing air through spoke holes It's my first time setting up tubeless. The tyre seems to have seated fine, but I'm losing air through three of the spoke holes when I go much above 20 psi. Details:

new rim, new tyre (new bike in fact)
29&quot; DT Swiss M 1900 Spline - tubeless ready
2.3&quot; Minion DHF - tubeless ready

I've added more sealant (must be getting near 200ml now) and shaken it about, concentrating on the leaking areas; air has stopped leaking but that might be the loss of pressure - down to 10-15 psi I think. Will leave it to sit overnight at the lower pressure and see what happens in the morning when I add air.
But in my limited reading so far I haven't seen this specific problem mentioned. Wondering if I'm wasting my time trying to seal this, and instead have a problem with the rim tape or even a defective rim?
EDIT: just for clarity - it's a tubeless-ready rim, factory taped, which I'd have hoped would rule out any errors of tape selection or technique.
It seems like there is a problem with the rim tape. The tape should seal the spoke holes without milk. Try cleaning the rim and replacing the tape if it is still loosing pressure.
