Can't pair testnet wallet with testnet dojo about samourai-dojo

[notmandatory]

I think it's failing with below exception, I confirmed the 75wg.onion address is correct and is where I login to the dojo admin via tor browser.

[LaurentMT]

the api key is included in the qr code.
did you use the V3 onion address for the pairing?

[notmandatory]

Hi, yes I used the v3 onion address to connect to the admin web server:

$ sudo ./dojo.sh onion
API hidden service address (v3) = 75wg<redacted>.onion

should I connect to the dojo admin page with the v2 address and re-pair a new wallet from the QR code that page gives me?

[notmandatory]

I tried pairing with v2 tor address and I'm getting the same exception.

API hidden service address (v2) = idx<redacted>.onion

Nope. Samourai Wallet requires to use the V3 onion address. I just wanted to be sure that it wasn't the cause of your issue.

I've done a test with a Dojo 1.2 testnet instance and an old side-loaded samourai wallet. The wallet was able to connect to the Dojo (successful authentication and creation of the xpubs).

From the elements posted here, I would say that your Dojo hidden service seems fine (you can connect to your Dojo through the maintenance tool). It looks like a network/tor issue within the wallet.

Anyway, here are a few things that you can check on Dojo:

• Is your Dojo fully synced? (do you see the same value for the "blocks" attribute in the "API" and "PushTx" tabs of the maintenance tool?)
• Do you see errors in the logs of dojo?
  • error logs of Dojo API: dojo.sh logs api -d error -n 500
  • error logs of Dojo tracker: dojo.sh logs tracker -d error -n 500

[notmandatory]

I think my dojo is fully synced, the API tab returns this:

{
    "uptime": "11:02:43",
    "memory": "67 MiB",
    "ws": {
        "clients": 0,
        "sessions": 0,
        "max": 0
    },
    "blocks": 1578985
}

for api -d error -n 500 I only see a few old expired jwt token errors, but I do get those some times and just logout and back in.

I also see this error for tracker -d error -n 500, but it's from about 10 hours ago, so not sure if it's relevant.

I'll try debugging this on the wallet side.. and if I still can't figure it out I'll open an issue in the wallet repo. I'm using a fairly old phone (android 5.1) so maybe that's causing an issue with the TOR connection. thanks!

[LaurentMT]

Everything seems fine. It really looks like an network/tor issue on wallet side.

[notmandatory]

👍 I'll also try with a newer phone and see if that behaves any better. I also didn't see anything in the wallet or dojo docs about only using the V3 TOR address, maybe good to mention that V3 is required.
