Anyhow, I think the error is on the first thing you're mentioning, about the SSL. My node run exclusively on Tor and does not use SSL certificate for the connection.

If you don't use SSL, you don't need to give us a certificate. We only use HTTPS with Tor if you give us a certificate. Else we'll try to connect to your node over HTTP for Tor then.

So maybe it will work if you simply leave out the certificate?

So are you saying I should run CLNRest over HTTPS? How I can do that?

No, you don't have to but you could. I assumed you would run it over HTTPS since it's the default of CLNRest:

--clnrest-protocol: Specifies the REST server protocol. Default is HTTPS.

Yes I tried as well leaving the cert empty and I get a different error:

1s	[cln]	ERROR	could not connect to CLN: invalid json response body at http://hidden.onion:2104/v1/invoice 
reason: Unexpected token < in JSON at position 0
1s	[cln]	ERROR	failed to attach wallet

In the JSON I've multiple runes and the one in position 0 does not have any restriction (and is there by default). The rune I've created and using is in position 1 and has the correct restrictions:

 {
         "rune": "hidden",
         "unique_id": "1",
         "restrictions": [
            {
               "alternatives": [
                  {
                     "fieldname": "method",
                     "value": "invoice",
                     "condition": "=",
                     "english": "method equal to invoice"
                  }
               ],
               "english": "method equal to invoice"
            }
         ],
         "restrictions_as_english": "method equal to invoice"
      }

So is maybe SN script looking at the rune in position 0 only and giving back that error? Should I edit the JSON and switch rune positions? Or what else could I try?

Your rune seems to be fine. We only try to connect when we verified that your rune is properly limited to method=invoice. We then use this rune with the Rune header as mentioned here and as you can see here. We don't do anything else to it.

The error invalid json response body at http://hidden.onion:2104/v1/invoice reason: Unexpected token < in JSON at position 0 means that we connected to your node successfully but it didn't return JSON as expected.

Do you get a valid JSON response when you do a request from the same machine with cURL? Try this:

$ curl -X POST http://localhost:2104/v1/invoice -H "Rune: <your_rune_here>"

🤨

Something seems to be wrong with your node. Looks like CLNRest is not running? I am not familiar with Umbrel unfortunately. Looking at the Umbrel docker-compose config for CLN, I wonder why they run CLNRest separately. Maybe that's related?

Since v23.08, it's built-in so they should add --clnrest-port during start to enable it which they don't.

It is maybe using a different port?

Does make sense to edit the docker-compose.yml file and add under command: for example:

--clnrest-port=${APP_CORE_LIGHTNING_DAEMON_IP}: 2104

You can for sure try. But try this:

--clnrest-port=2104

or use 3010 as the port since according to the docs, that's common

can't really find the same file inside the node 🤔

Oh, sorry that I left you hanging, I forgot to reply.

Which file? The docker-compose file? Does Umbrel not have a way to pass startup arguments to CLN?

Sorry that I can't help you here further. As far as I can tell, there seems to be something wrong with your node (or reverse proxy if you are running one). I think you should reach out to Umbrel for support. Maybe they have a Telegram group?
