IFTTT issues

Dear Sirs,
I do not get notifications when someone rings the bell. To bypass it I have used, more than a year, IFTTT applets (also with HUE) but recently I cannot use anymore. The login enters in loop when connecting the applets. Thanks in advance for your help. regards

Did you already try to newly the Nuki Opener service via https://ifttt.com/nuki_opener?
(Go to Settings → Remove and then Connect again; only “Reconnect” sometimes does not help)
