My setup is a little bit complicated and I'm almost sure that my problem is port related.
So I'm running Mac OS X 10.13.4 with Parallels Desktop with a Ubuntu 14.04 VM. I managed to setup bitcoin core in the VM, on top of it I installed c-lightning and managed to fund it with btc (All is happening on the testnet) which I used to open one channel with some random other node. Everything is perfect for now.
Because I want to use the LApp for WordPress Lightning-Publisher I Installed lightning-charge and started an HTTP server running on the default port 9112. All of my ports are correctly forwarded and in my bitcoin.conf file I have allowed all ips. If I run Mozilla in my Ubuntu VM and go to
http://api-token:mySecretToken@localhost:9112/info everything is fine, but when I try this on my Mac I get
Can't open the page because the server unexpectedly dropped the connection. If I try using my external ip it's the same thing.
Using several sites to check if my ports are correctly forwarded I get that all corresponding ports are open (18332 for BTC core, 9735 for c-lightning and 9112 for lightning-charge).
Here is my bitcoin.conf
testnet=1 server=1 rpcallowip=0.0.0.0/0 rpcuser=someuser rpcpassword=somepass addnode=220.127.116.11 addnode=18.104.22.168 addnode=22.214.171.124 addnode=126.96.36.199 addnode=188.8.131.52
here is my lightning config
network=testnet alias=IVCHOBIVCHO port=9735 rgb=008000
Neither Ubuntu, nor my Mac are under any kind of Firewall. My router is TP-Link
