Electrum Personal Server & Sparrow Wallet

Hi guys,

I'm trying to link my Sparrow wallet (on Windows 10) to my Electrum Personal Server (which was at first linked to my Electrum Wallet), though TOR. I'm stucked with a "failed to subscribe to path: ../0/0" error.

My Bitcoin Core Node (v25.0) is connected via TOR through a SOCKS5 (127.0.0.1 - Port: 9150).

In the config.ini file of my Electrum Personal Server, the master public key (zpub) is well entered, the bitcoin-rpc settings are 127.0.0.0 - Port: 8332, and the electrum-server setting are 127.0.0.1 - Port: 50002. Moreover, the tor settings are localhost and 9150.

In the bitcoin.conf file of my Bitcoin Core, there's:

Code:

server=1
txindex=1
listen=1
proxy=127.0.0.1:9150
bind=127.0.0.1
onlynet=onion
dnsseed=0
dns=0
rpcuser=A
rpcpassword=B
rpcbind=127.0.0.1
rpcallowip=127.0.0.1

Finaly, my Sparrow wallet settings are: Private Electrum Server / 127.0.0.1 - Port: 50002 / SSL / Use Proxy - 127.0.0.1 - Port: 9150.

When i launch my Bitcoin Core node, it's connected to peers through TOR. -> Everything seems okay.

When i launch the config.ini file of my EPS, the master key and the first 3 addresses are well written. It connects to the mempool, then is "listening for Electrum Wallet on ('127.0.0.1', 50002)" as it did when I used Electrum is the past. -> Everything seems okay.

When i launch the Sparrow wallet and i try to "Test Connection" into Files > Preferences > Server, it's written:

Code:

Connected to ElectrupersonalServer 0.2.4 on protocol version 1.4.
Monitoring X deterministic wallet, in total Y addresses.

-> Everything seems okay.

However, once i click on the bottom right button to really connect Sparrow to my EPS / Node, my EPS control pannel says:

Code:

WARNING: Address not known to server, hash(address) = ZZZ
Check you've imported the master public key(s) correctly. The first addresses of each key are printed out on startup.

It's also making me stuck, 'cause the first 3 addresses from the master public key (zpub) are okay.

In my Sparrow wallet, it's written:

Code:

Failed to subscribe to path: ../0/0

and

Code:

Error loading transactions: Failed to subscribe to path: m/0/0

Deeper, in my Sparrow log file, it's written:

Code:

Failed to subscribe to path: ../0/0
[...]
I/0 error during a request processing
[...]
Error reading response: Could not connect to server at ssl://127.0.0.1:50002
[...]
java.io.IOException: Could not connect to server at ssl://127.0.0.1:50002

I checked everywhere on the internet and didn't find anything.
In this post: github .com/sparrowwallet/sparrow/issues/430, a guy had the same issue than me and said he succeeded by adding the 4th master public key of the Sparrow wallet in the config.file of EPS; which i did. However, i still had the same problem; even if i added the 14 master public key in the config.file (with the following format:

Code:

ad1 = zpub1..
ad2 = zpub2..
ad3 = zpub3..
...

In this same post, the EPS dev' said we should check if the 50002 port is opened.
I did so: when i run "netstat -a", i've got 2 TCP - 127.0.0.1:50002 lines:

Code:

1 -> PCx:0 LISTENING
2 -> PCx:63968 ESTABLISHED

And, when i run "telnet localhost 50002" in CMD, it's written:

Code:

Connecting to localhost...

Then a new window "Telnet localhost" appears, without anything written inside. After a few seconds, the "C:\User >" appears again in this window.

Perhaps did i missconfig something, i'm not a pro. However, i do not have any idea:
-> my Node works well
-> my EPS is connected to my Node well
The problem seems to be between my Sparrow wallet and my EPS, i guess.

Also, have you already been stuck with Sparrow like this?
If so, how did you succeed to make it run?

Any help will be appreciate; thanks guys
