Cannot connect wallet to my own ElectrumX server

[velhoti]

Hi all.

I installed the ElectrumX server but i can not connect to my server from my electrum wallet. I am behind CG-NAT, so it is a pure Tor server. I create the tor service in /etc/tor/torrc:

Code:

.
.
.
HiddenServiceDir /var/lib/tor/electrumx/
HiddenServicePort 50001 127.0.0.1:50001
HiddenServicePort 50002 127.0.0.1:50002
.
.
.

and this is my ElectrumX configuration file:

Code:

DB_DIRECTORY = <path>/electrumx/db
DAEMON_URL = <user>:<password>@127.0.0.1:8332/
COIN=Bitcoin
DONATION_ADDRESS=1LM9kqiRPMavcgocXmexw5vNn2XhVSi5Rq
BANNER_FILE= <path>/electrumx/banner
SERVICES = rpc://127.0.0.1:8000,wss://:50001
REPORT_SERVICES = wss://y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001
SSL_CERTFILE =  <path>/electrumx/server.crt 
SSL_KEYFILE =  <path>/electrumx/server.key
FORCE_PROXY = on
TOR_PROXY_HOST = 127.0.0.1
TOR_PROXY_PORT = 9050

The server is synced and have peers, the output of $electrumx_rpc getinfo:

Code:

{
    "coin": "Bitcoin",
    "daemon": "127.0.0.1:8332/",
    "daemon height": 732924,

        "subs": 0
    },
    "tx hashes cache": "0 lookups 0 hits 0 entries",
    "txs sent": 0,
    "uptime": "07h 18m 48s",
    "version": "ElectrumX 1.16.0"
}

I want to connect using two methods, the first is via Tor, i am trying the command:

Code:

$./electrum-4.1.5-x86_64.AppImage -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001:t -p socks5:localhost:9050

the second method is to use a ssh tunnel from other PC inside my own network to connect via rpc:

Code:

$ssh -p <port> -L 8000:127.0.0.1:8000 <user>@192.168.0.104
$./electrum-4.1.5-x86_64.AppImage -1 -s localhost:8000

Using both methods the dot indicating connection in electrum wallet stay red and do not connect to the server. I am using a new wallet to test . Do i missing some configuration or using some command with wrong sintaxe? Any help is welcome.

edit: Also https://1209k.com/bitcoin-eye/ele.php is showing my node as "Closed".

Can you try to change your Daemon URL into localhost instead and edit the services replace them with the configuration below?

Code:

DB_DIRECTORY = <path>/electrumx/db
DAEMON_URL = rpcusername:rpcpassword@localhost
SERVICES = tcp://0.0.0.0:50001
COIN = Bitcoin
PEER_DISCOVERY = off

Also, try to change Peer_discovery on or off and check if your server will show up automatically in "electrumx_rpc peers".
Check this Reddit post below to get some idea about configuration.
- https://www.reddit.com/r/Electrum/comments/ggmduo/electrumx_over_tor_configuration_help/

I search more and it seems it's not easy to set up ElectrumX through TOR I have never seen someone succeed or share a guide on how they succeed in configuring their ElectrumX with TOR.

With this configuration i lost the RPC connection, adding

Code:

SERVICES = tcp://0.0.0.0:50001,rpc://

i can run "electrumx_rpc peers" wich shows a list of peer only if  PEER_DISCOVERY = on.

I've tried this already, not worked, i believe is outdated, old electrum version.

Run the server through ssh tunnel is a half solution already.

Unfortunately the suggested conf file not worked, the same behavior trying to connect be through ssh tunnel or TOR.

Using your default config, try to connect using this:

Code:

$./electrum-4.1.5-x86_64.AppImage -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001:s -p socks5:localhost:9050

If that doesn't work, try to post your Electrum and Electrum server logs.

the ElectrumX log:

Code:

.

.
Apr 22 01:14:26 <machine> electrumx_server[5086]: INFO:PeerManager:accepted new peer vps5.hsmiths.com from coins.py
Apr 22 01:14:26 <machine> electrumx_server[5086]: INFO:PeerManager:accepted new peer electrum.emzy.de from coins.py

Apr 22 01:14:37 <machine> electrumx_server[5086]: INFO:PeerManager:blacklist from https://electrum.org/blacklist.json has 689 entries

the electrum wallet prints nothing, neither i found logs.

Possible missing user and password.

Add -v when you execute the command, the log will be outputted into the CLI.

Code:

$./electrum-4.1.5-x86_64.AppImage -v -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001:s -p socks5:localhost:9050

Code:

Apr 22 01:14:27 <machine> electrumx_server[5086]: INFO:PeerManager:detected SOCKS5 proxy at 127.0.0.1:9050, auth: none

Possible missing user and password.

I believe there isn't any something wrong about that.

[velhoti]

Found the solution, following the reddit post:
https://www.reddit.com/r/Electrum/comments/ggmduo/electrumx_over_tor_configuration_help/
but with a slight difference in the command:

Code:

./electrum-4.1.5-x86_64.AppImage -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001:t -p socks5:localhost:9050

the connection must be throught TCP, not explicitly TOR.

I still investigating if use TCP+SSL instead TOR have implications in privacy, but works.

thanks for all help

[vv181]

Yes but you are connecting over an unencrypted network.

The reason why I suggest using :s instead of :t[1] is to make the Electrum wallet make an SSL/TCP connection as OP ElectrumX configuration(wss://:50001)[2].

If you are following the Reddit thread, with

Code:

SERVICES = tcp://127.0.0.1:50001,ssl://127.0.0.1:50002,rpc://127.0.0.1:8000
REPORT_SERVICES = tcp://xxxxxxxx.onion:50001,ssl://xxxxxxxx.onion:50002

Code:

./electrum-4.1.5-x86_64.AppImage -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50001:t -p socks5:localhost:9050

Then it is should work, but you are transferring data over an unencrypted protocol, which surely not the recommended way.

[1] https://electrum.readthedocs.io/en/latest/protocol.html?highlight=tcp#server-peers-subscribe
[2] https://electrumx.readthedocs.io/en/latest/environment.html#services

the connection must be throught TCP, not explicitly TOR.

The connection is using TCP over Tor.

I still investigating if use TCP+SSL instead TOR have implications in privacy, but works.

Other than the two references above, try to see https://electrumx.readthedocs.io/en/latest/HOWTO.html#creating-a-self-signed-ssl-certificate

[velhoti]

it works also with ssl connection, i configured already SSl certificates, with the command:

Code:

./electrum-4.1.5-x86_64.AppImage -1 -s y32svarehxecrpvg62upqq7lgqhcrr3m35y4cqogy4nubsic2y3fofyd.onion:50002:s -p socks5:localhost:9050

at least not plain text

~

Yup that's good

That should explain why the OP configurations doesn't work. I thought the wss:// electrum server protocol can be used with Electrum wallet tcp/tls config.

[velhoti]

I was inspecting the electrum wallet code:

Code:

help="set server host:port:protocol, where protocol is either t (tcp) or s (ssl)")

Source: https://github.com/spesmilo/electrum/blob/bb2e4109422dc46652bc6579bcfc8149e3c86758/electrum/commands.py

There is no option to create a WSS connection, only TCP and SSL (through tor). Then i presume it is the correct configuration.
