Just to see if there was something Europe wide, I did some tests, because I’m in the UK. I was able to log in to IFTTT. I was able to add a new applet, and link it to Blink Europe, and test it successfully. I then ran a script that logs into the Blink API server, and it worked as normal, and I also logged out of my app, and clicked the forgotten password link that appears when you log out. I got the email within about two minutes. Not sure what your issue is, but it doesn’t seem to be European wide.
I suppose your best course of action now would be to log a support ticket.
