Summary0010208: Wallet in Dev mode can't connect to local Exchange
DescriptionHi,

I got the local exchange deployed now but when I try to connect the wallet I get this error:

{
  "context": [],
  "cause": {
    "details": {
      "when": {
        "t_ms": 1753297449987
      },
      "hint": "HTTP request failed.",
      "requestUrl": "http://bank.lanchaos.net/taler-integration/config",
      "requestMethod": "GET",
      "timeoutMs": 60000
    }
  }
}

Trying to access the requestUrl manually returns this:

{"currency":"KIWIS","currency_specification":{"name":"KIWIS","num_fractional_input_digits":2,"num_fractional_normal_digits":2,"num_fractional_trailing_zero_digits":2,"alt_unit_names":{"0":"KIWIS"}},"name":"taler-bank-integration","version":"5:0:5"}

The wallet works fine with the Online Taler Demo...
Developer Mode is enabled as well as HTTP Requests allowed in the Wallet
TagsNo tags attached.

How exactly do you try to "connect the wallet to the exchange" here? Also, does it work with the other wallet(s)?

I log into the bank, click "To Taler Wallet", choose 10 of the 100 Kiwis I have and click continue... That's when the error comes up...

That workflow works fine when using the Taler Demo bank and transfer to the wallet... Got Kudos on there without issues

Ok, thanks for explaining. Sebastian is currently traveling, we'll try to reproduce "soon" once we see him in person... (likely will take 2-3 days). I suspect some config/base-URL is set incorrectly, but hard to reproduce without setting up ourselves (and I won't have time for the next few days).

I can always just give you access to my VM....

I'll rerun the setup over the weekend but with public IP and TLS... Just to see if that makes a difference...

Ran a fresh installation of the Regional Currency without Fiat connection today but this time with public IP and TLS...

Works fine.... No issues with transferring coins from Exchange to Browser or mobile wallet....
