Google TTS can not authorize

I can not get Authorization Code by using Anmelden – Google Konten

What do i put in URI?

Any updates?

Reading this I also realised that I haven’t heard my OH reminders for a while.
Should this issue affect the already authorised connections or is it related to the new authorisations only?
It is certainly before 28/02 since I had my garbage reminder

I can’t tell. I just know that getting an AuthCode by Browser is not working anymore as described here which has nothing to do with OpenHub itself. But I can’t find any information at all how to get an Authorization Code by Browser.

I made a few JARs using a different redirect_uri which makes it possible to get an authorization code for getting the tokens, see this openhab/openhab-addons#12455 (comment).


I receive this in new solution
