fatal error: could not connect to bitcoind using json-rpc

[Talej]

Having difficulties working out what I have wrong connecting to a remote bitcoind.

Actual issue from the log seems to be ** unexpected end of stream on http://192.168.8.118:18333/...**

Sorted this out.

Needed to add rpcallowip=0.0.0.0/0 into bitcoin.conf

Needed to add rpcallowip=0.0.0.0/0 into bitcoin.conf

That's new, what version of bitcoind are you using?

[Talej]

v23.0.0

On an unrelated note is it possible to run eclair API over SSL? I haven't been able to find anything in the config options for this

[t-bast]

v23.0.0

Got it, that's why you're seeing the issue, we do not yet officially support bitcoind v22 or v23 (we're always waiting for a point x.1 release, which didn't happen for v22 but should probably happen soon for v23), so we haven't updated our documentation accordingly yet.

On an unrelated note is it possible to run eclair API over SSL? I haven't been able to find anything in the config options for this

No, it really isn't designed to be exposed over anything else than localhost.
We have ideas on how to change that in the future while keeping access secure, but this isn't something we'll do in the short term.

I also use v23.0.0 and don't have this line in my config.
I believe this is only neccesary when you use anything else than 127.0.0.1/localhost for your connection.

Afaik if eclair and bitcoind run on the same machine use 127.0.0.1/localhost for everything.
If they run on different machines use:

rpcallowip=[eclair ip]/32

This would be much saver than opening it to all IPs

[Talej]

Agreed adding the specific IP would be safer. This is only for a testnet setup and all internal network so I'm not concerned

[Talej]

Thanks

Additional info:

• To diagnose bitcoin core RPC connections issues, try using bitcoin-cli first with the same parameters as in your eclair.conf file, in most cases it will help reproduce and fix the problem.
• If you need to access bitcoin core or eclair RPC from remote machines we'd recommend that you setup SSH tunnels instead of explicitly allowing remote IPs. This is also what bitcoin core recommends and it's much better than implementing SSL RPC (bitcoin core used to have SSL encrypted RPC and removed it).
