fints.ing-diba.de seems no longer to authenticate

[jmuxfeldt]

endpoint = 'https://fints.ing-diba.de/fints/' no longer authenticates since about 10 days. Has anyone else had this problem? I've tried everything, including logging into the online banking via browser.

The connection had been working perfectly until about 10 days ago. Something has changed. I did do a global update of homebrew, which would have updated python too.

The connection does work using Open-Fin-TS-JS-Client, so there seems to be some new incompatibility with the python library.

I have also been able to authenticate using a php fints library, so something must have happened to the DiBa's api, which python-fints can no longer handle

For me ING-DiBa still works. I've current (3.0.1) version of this library.

Thanks for the feedback.
I didn't change anything in my script, so this is all a bit mysterious, and all I can imagine, is that some python libraries used by python-fints got updated when I did my homebrew upgrade. Running the debug script hasn't given me any more details either, other than the same old ".FinTSDialogInitError: Couldn't establish dialog with bank, Authentication data wrong?".

Googling this a bit, it seems that ING is slowly switching from https://fints.ing-diba.de/fints to https://fints.ing.de/fints

[jmuxfeldt]

@michaelgruenewald Thanks so much. That fixed it. I had actually done a lot of googling myself, and I also get a regular update of the fints address list, since I am registered. Even stranger is the fact that both a php fints library and Open-Fin-TS-JS-Client were working, so I had no reason to suspect an address change. Really, you saved the day here, since I had reverted to a less good solution.

I just checked my URL - I'm already using the new one, sorry for the confusion.

I use https://github.com/hbci4j/hbci4java/blob/master/src/main/resources/blz.properties as source
and here the URL got updated in 2019: hbci4j/hbci4java@d7f3d1c

But: in "Bankenliste" distributed by ZKA there is the still the old URL.

"But: in "Bankenliste" distributed by ZKA there is the still the old URL".
Exactly.
