Monero wallet gui on Linux not connecting to Start9 monero 'remote note'/daemon

I am running on Mint using the app image of monero wallet GUI. I followed the directions here: monerod-startos/docs/guides.md/monero-gui.md at master · kn0wmad/monerod-startos · GitHub

I have not set up authentication since this is only needed local. I have tried the local (my preferred option) using the '‘Wallet RPC URL (LAN)’ and onion ('Wallet RPC URL (Tor). I tried changing with the port # from the instructions said to that on the properties listed after each address in my start9 monero app.

what am I missing/doing incorrectly?

Hi @BasicSkillset, can you confirm that you are using the Restricted RPC URL found on your service’s Properties page, rather than the Wallet RPC URL? If not, that will explain the error.

I have the same issue. My PC is using Ubuntu. I followed the same guides listed in the OP but my Monero GUI refuses to connect to “remote” node, on my own network. I am using Restricted RPC URL.

this worked. thank you for that. do you know what the unrestricted “Wallet RPC URL (LAN)” is for? Maybe I am missing where the instructions are on all this. Maybe you can help on my next question:
it seems Monero GUI only lets onr mine with a local daemon so I will not be able to mine with this app using Start9. Is there a wallet that will?
