comdirect: Error during dialog initialization, could not fetch BPD.

[tovolkmar]

Hi,

since today i get the following error for comdirect. It worked like a charm till today.
I'm not sure was wronge, but it seems related to a PSD2 change?

Error during dialog initialization, could not fetch BPD. Please check that you passed the correct bank identifier to the HBCI URL of the correct bank.

Thanks for your help,
Tobias

Someone mentioned in #72 that this library currently doesn't support requiring Strong Customer Auth that early in the process yet. But I found this thread indicating comdirect's process is broken anyway at the moment.

I have similar problems with DKB. Since the 13th of September it worked like a charm. Starting the 14th of September (the day PSD2 started) I got the following error messages:

09/14/2019 00:05:37 ERROR: Dialog response: 9050 - Die Nachricht enthält Fehler.
09/14/2019 00:05:37 ERROR: Dialog response: 9800 - Dialog abgebrochen
09/14/2019 00:05:37 ERROR: Dialog response: 9010 - Die angegebene Bankreferenz/Dialog-ID ist nicht gültig.
09/14/2019 00:05:37 ERROR: Dialog response: 9010 - Auftrag wegen genereller Fehler in Auftragsnachricht nicht verarbeitet.

Did not debug it yet but my guess is PSD2. The problem for me is: I used it to passively monitor my bank transactions and inform me every time a transaction was performed on my account. If I have to enter a TAN each time it logs in I can forget this service. Does anyone know if PSD2 enforces TAN authentication each time you login via HBCI?

Unfortunately i've experienced the same issue on comdirekt and dkb. I've already registred my software at the ZKA, but using the product_id didn't changed the behavior of the lib.

I have the same issue and get the "You should register your program with the ZKA and pass your own product_id as a parameter" warning. @crawler64: "Is this easy to get as a privat person?" Can you provide a link where you registered and was it hard to get?
Thanks in advance.

[raphaelm]

This warning is issued by the library. If you use your system in production, you should do that. However, it is probably not the reason why your connection fails.

Here's info on the registration: https://www.hbci-zka.de/register/prod_register.htm

Thanks for your answer. My code was running fine until last week. the follow up errors I get are:
Dialog response: 9050 - Die Nachricht enthaelt Fehler.
Dialog response: 9800 - Dialog abgebrochen
Dialog response: 9010 - Die angegebene Bankreferenz/Dialog-ID ist nicht gueltig.

Hi,

I get the following error with comdirect:

I use the last version from the PSD2 Branch. The PIN is definitely correct and my connection to the Volksbank works fine.

Does somebody has any idea?

Can anyone confirm this or has a solution for this problem?

[elohmeier]

@drmhessler I had the same error, did you try to use the psd2 branch? It worked for me then using photoTAN.

@drmhessler I had the same error, did you try to use the psd2 branch? It worked for me then using photoTAN.

I can confirm that I have the same issue that @drmhessler has and I did try the psd2 branch as well as 2.2.0 using Sparkasse.

[drmhessler]

with the PSD2 branch I was able to get the transactions from comdirect.

[raphaelm]

Closing this issue because it's about comdirect and from all I can see comdirect works with the PSD2 branch already.
