I setup a full node a few weeks ago and successfully connected sparrow wallet from a different PC but on same network. It connected fine until yesterday and now sparrow won't connect. 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?
By same network, do you mean both PC is on same LAN/local area network? If yes, either try
1. Configure DHCP (which already suggested) and make sure you entered correct local IP of your node on your sparrow wallet.
2. Check firewall configuration on both device. There's rare case where Windows Firewall broken or it's rule changed after Windows update.
