[Taler] Withdrawal is never confirmed

[Florian Jung]

    Hi everyone,
    I once again got
        a bit further with my taler setup, and my android wallet finally
        talks to my exchange :).
    However, I just
        tried and failed to withdraw some moneys into my wallet. This is
        what I tried in short:
    
    In my android
        wallet, i selected my exchange and selected "withdraw money". I
        selected to get 10 MANA (which should be possible with the 1MANA
        coins i configured), and the app showed me the withdraw
        instructions. ("wire this much money to DE827320 and put this as
        a payment reference").
    Then, I went to
        my sandbox and executed:
    
    > $
            libeufin-cli sandbox bankaccount
          simulate-incoming-transaction jrluser --debtor-iban DE01234
          --debtor-bic FAKEFAKE \
    >         --debtor-name "Das
          System" --subject "Taler Withdrawal
          9F3TK9ZGYXNFE06M9KD8PG51GB23WBRVHVF5056CV8KR412384N0" --amount
          10
    
        
    (jrluser is the account name of
          the account i shall wire the money to)
    
    
    However, my wallet does not
          confirm the transaction. it seems like the exchange doesn't
          see it, but I don't know how to debug this. Can I ask my
          exchange for a list of transactions / reserves known, and
          about their withdrawal status or something?
    
    
    More debugging info (and some
          questions) follow below:
        
    > $
        libeufin-cli sandbox bankaccount transactions jrluser
    
    > {
    
    >  "payments" : [ {
    
    >     "accountLabel" :
      "jrluser",
    
    >     "creditorIban" :
      "DE827320",
    
    >     "creditorBic" :

    In nexus, I can confirm this
      too:

          accounts transactions myconn_jrluser
        
    > {

        {
      
    >     "amount" :
        "MANA:10",
      
    >

    Also, the nexus keeps spamming
        repeatedly:

    I'm a bit confused about the two
          taler facades, and about the "Please clarify" message.

Is it normal that this message repeats infinitely? (With the fetch and submit tasks scheduled once per second).

I would be really happy about any help on this matter, as I don't know how to proceed from here.

Thank you for your time and have a good night,

Florian
