Postbank: Call to undefined method - why?

[1manfactory]

Hello,

I am checking my account balances from a local Debian server.

URL: https://hbci.postbank.de/banking/hbci.do

But the same files (with identical init settings and credentials) won't work on a German based remote server. They lead to a strange error.

Error: Call to undefined method Fhp\Segment\HITANS\ParameterZweiSchrittTanEinreichungV6::isEinschrittVerfahrenErlaubt() in /inc/vendor/nemiah/php-fints/lib/Fhp/Protocol/BPD.php:200

Strange. Suddenly, though I did not change a thing, it works.

Leaves me a bit puzzled. I don't like it when something is "fixed" by magic. I'd prefer to know exactly what happened.

Any ideas?

If you can't reproduce it anymore, you can't debug.

We would need to know if this is also your BPD.php:200 line at the time when it fails. And then dump the value of $tanParams there.

Yes. Lines/files are identical.
But it never get's to the var_dump inserted in line 201. Simply timeout error after 15 seconds.
This is the complete exception_handler dump. Maybe this helps.

That's now a completely different error though -- BDD::extractFromResponse() isn't there anymore. Please file a new bug if that persists, including a description for how to reproduce it..

Fyi: Postbank had DNS problems in the last few days, this is also what the last error message you posted says.
