I do not use Tor on Bitcoin Core so would guess getting inbound and outbound connections will take time. Post your bitcoin.conf here because it may potentially improve after putting a few lines.
It says my .onion addres is reachable at bitnodes.io yet no inbound connections in GUI on peers. I only get outbound connections. Does it take a couple of hours before inbound connections can find me? The outbound connections I get it after 5 mins. Have only runned my node for 45 mins with Tor, and yes I'm fully synced with the blockchain.
If somone could help, It would be appreciated🙏
