Let's just go to their github issues and post there?

Coracle looking for relays forever might be the case with brand-new keys. 

Nostrudel has everything working in their 'next' version at 'next.nostrudel.ninja', on main branch of theirs you must use bunker URL for now - click 'Connect App' in nsec.app, copy bunker URL, then select Advanced -> Nostr Connect / Bunker option in Nostrudel.

There is also Snort, worked fine last time I checked, just choose 'Already have an account' and paste your name@nsec.app
