Bitcoin Core – Can’t get inbound connection to my node

I recently set up a Bitcoin Core Node on my Raspberry Pi. I’m configuring a node using bitcoind, but I can’t get an inbound connection. Here are the steps I took:

1. The firewall is turned off.
2. I set up port forwarding to port 8333 on my router.
3. Added listening=1 and discover=1 to bitcoin.conf.
4. I created a static IP address on my router.
5. I rebooted my router and Bitcoin.
6. I checked the ports blocked by my ISP and 8333 was not blocked.

When I check bitnodes.io, it says it can’t connect to port 8333. Any help would be greatly appreciated.
