I found the answer on
https://github.com/ElementsProject/lightning/blob/master/doc/lightningd-config.5.md

If 'PORT' is not specified, the default port 9735 is used for mainnet (testnet: 19735, signet: 39735, regtest: 19846). If we can determine a public IP address from the resulting binding, the address is announced.

For testnet I must use 19735 instead of 9735.

Have you tried using a port different from 9735 already? Is there a change there's another port open (netstat let's you see a lot of info based on searching for the specific job or the name that would be given to any other port that's open).

Hello,

I'm able to connect to bitcoind remotely from my laptop using following CURL command:

curl --user user:password --data-binary '{"jsonrpc":"2.0","id":"curltest","method":"getblockchaininfo","params":[]}'  -H 'content-type:text/plain;' http://1.2.3.4:18332 -v

but I'm not able to call the lightingd remotely from my laptop using following CURL command:

curl --user user:password --data-binary '{"jsonrpc":"2.0","id":"curltest","method":"listpeers","params":[]}'  -H 'content-type:text/plain;' http://1.2.3.4:9735 -v

Trying 1.2.3.4:9735...
* connect to 1.2.3.4 port 9735 failed: Connection refused
* Failed to connect to 1.2.3.4 port 9735 after 517 ms: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 1.2.3.4 port 9735 after 517 ms: Connection refused

Lightningd is running and I opened 9735 on the firewall.  I can successfully run "lightning-cli -testnet listpeers" on the node locally.

When running "netstat -anpe | grep "9735" | grep "lightning"" I see there's already an established session on 9735.  

tcp         0      0 1.2.3.4:34918        5.6.7.8:9735       ESTABLISHED 1000       41663      1508/lightning_conn
tcp6       0      0 :::19735                :::*                    LISTEN      1000       40773      1508/lightning_conn

Should I use another port for json-rpc access and leave 9735 for node/peer communication?

I already added 0.0.0.0/0 as rpcallow for testing in the bitcoin.conf file.

Anyone know how I should access lightning json-rpc remotely?

thanks,
Pecheur

Also, I know there's "lightning-cli connect" to connect remotely using the CLI.
But I would like to use JSON-RPC calls instead.  First using CURL then using a nodejs request.
