There is a one-time payment of 1 satoshi your node needs to be able to pay before it can access the Loop service. That payment seems to have failed and you need to try again. What software platform are you using? Umbrel, MyNode, self-built?

I had no idea about that requirement. I am with Umbrel. Do you have a procedure on how to do it? Thank you.

See https://docs.lightning.engineering/lightning-network-tools/lightning-terminal/loop-fees.

I'm not an Umbrel user, so I hope this works. Might need some trial and error. Or you might need to get support from the Umbrel team if a command doesn't work:

• Log into the Umbrel terminal
• Find the docker process (lightning-terminal) with docker ps, copy the container ID that looks something like 340a5b0839f1
• Open the lightning-terminal container with docker exec -it <container_id_from_previous_command> /bin/bash
• Find out where the pending token is located: pool --tlscertpath "/data/.lit/tls.cert" --rpcserver localhost:8443 --macaroonpath /data/.loop/mainnet/loop.macaroon listauth, look for the value of file_name, should be something like /data/.loop/mainnet/lsat.token.pending
• Delete the pending token: rm <full_path_from_above_file_name, so for example rm /data/.loop/mainnet/lsat.token.pending
• Try again

Though remember, this will only work if you have active channels and are able to pay the 1 satoshi for the token.

Closing the issue since it's not a problem with lightning-terminal. Feel free to continue the thread if things don't work out.
