Gzuuus … you were right all along. My timestamp was not formatted properly.
BUUUT in my defense, NDK event.publish() doesn’t report errors from relays … and relays also don’t report useful errors when fail to write.
Had to deconstruct NDK to even get a stupid error logged like this (as returned from my relays) :
“wrong index for variant”
Nostr sucks for debugging.
