comdirect: Die Nachricht hat nicht die erwartete Nachrichtennummer.

[msix81]

I tried to configure the FinTS Importer for a comdirect account, but received the error message Die Nachricht hat nicht die erwartete Nachrichtennummer. unfortunately.

Configuration (done via UI):

The chosen Two-Factor Method doesn't really matter. My bank supports 901 and 902 (as confirmed by the error message when selecting another one), and the error is the same for both.

Any ideas?

Full stacktrace:

Hi @msix81,
could this here be the problem?
I suspect the error might occur because teh form is effectively submitted twice in this scenario.

You were right, thank you! I had to start a new browser session and not click on any "Proceed" button, but just wait for a couple of seconds. Now I am seeing another error ("cURL error 7: Failed to connect to localhost port 80 after 0 ms: Connection refused"), but I guess I have to follow up that one separately.
