When I setup the node I followed the tutorial on bitcoin.org and did the port forwarding. The node I still receiving incoming connections fine. I followed the sparrow tutorial and all info is still correct.
The node is running on a PC with windows 10 and sparrow is on a pc with windows 11. I haven't changed anything but sparrow just won't connect now. Any suggestions?
How about the guide above it about setting a static IP:
bitcoin.org/en/full-node#configuring-dhcp?
By saying "
still receiving incoming connections", do you mean you're still getting "
Inbound" Peers or not?
Because if not, my best guess is your set 'rpcbind' IP address didn't match after getting a new IP address.
The node is definitely receiving incoming connections. It has 21 inbound right now and bitnodes shows it as accepting incoming. The WAN ip is automatic and has changed since I setup the node. But it looks like the internal ip's for the two PC's are static. Should I change that WAN ip to static?
Which IP do you use to connect Sparrow running on one machine to Bitcoin Core on the other? Your external / WAN IP or your local IP (192.xx... or similar)?
Again; opening ports in your router improves your node, since it can now accept incoming connections -
by other Bitcoin Core nodes. Not by light clients.
Sparrow can use the RPC interface running on 8332 to connect to a Bitcoin node but you don't (or at least definitely shouldn't) expose that to the public internet, as it would give everyone full access to the node (e.g. spending funds).
Therefore, Sparrow connection to a Bitcoin node (without Electrum) works when both are on the same machine and also if they're on a LAN & the 8332 port is opened in the
node's own firewall. Then you can access it through its local IP.
Here are the official instructions by the Sparrow team:
https://www.sparrowwallet.com/docs/connect-node.htmlNotice how they always mention local IPs; since connecting to Bitcoin Core's RPC interface remotely is basically completely out of the picture, anyway, they don't even mention that.

https://bitcoin.stackexchange.com/a/88948/119879I also just tried installing sparrow on the node PC and it won't connect to node either.
That's very weird. Is Bitcoin Core still running, fully synced and has the settings in its config file that are mentioned in the official guide?
