NOW=$(date -u +%Y-%m-%dT%H:%M:%S%z)
SIGNATURE=$(lncli signmessage "$NOW" | jq -r .signature)
JSON="{\"query\": \"mutation HealthCheck(\$signature: String!, \$timestamp: String!) { healthCheck(signature: \$signature, timestamp: \$timestamp) }\", \"variables\": {\"signature\": \"$SIGNATURE\", \"timestamp\": \"$NOW\"}}"
echo "$JSON" | curl -s --data-binary @- -H "Content-Type: application/json" -X POST --output /dev/null $URL

Thanks for sharing! FYI I tweaked for CLN/c-lightning here: https://gist.github.com/swissrouting/111d4a615d670ddf8d11eaa8a60eacca

thanks it works! I had to replace lncli signmessage with ~/umbrel/bin/lncli signmessage (Umbrel version 0.4.18)
