Hi,

I tried myself now and it works for me.

These kind of errors are in most cases network or environment related.

My best guess are these postnasal issues:

• If the environment you run the PHP script from have issues with resolving auth.api.swedbank.se. So dubble check you have working DNS settings and test if it can do DNS lookups.
• Have issues with connecting to the internet
• Some temporarily issue out of you control, e.g. on Swedbank's end.

In theory, even if I haven't observed this behavior from Swedbank, it's possible you could got this because the IP is blocked (temporarily) by Swedbank due to rate limiting or similar.

FYI. I have been testing for a while now, only was a few days I had the problem. It seemed to be something with the generation/retrieval of the QR code, but it was intermittent. After a few days, everything worked as it should, and the problem was gone. Nothing changed on my side. Can't tell what the issue was.
