Tl;dr:
Trying to create an AuthCode following the Url example of settings/services/org.openhab.voice.googletts google gives me an Error page 400: redirect_uri_mismatch instead of an AuthCode
This is openHAB 3.3.0.M6 running on debian buster
I had set up google tts in september 2021 and it had worked nicely for me since then. Yesterday it stopped in mid-talk, between one SAY and the other it stopped working.
First was:
Error initializing Google Cloud TTS service: An unexpected IOException occurred: java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: Buffering capacity 2097152 exceeded
and after that any attempt to say made a log line: Missing service configuration.
After a while there was an addition to that: Error fetching access token. Invalid authcode? Please generate a new one.
I went on the UI page, copied, edited the url for the authCode generation. Those were of the redirect_uri=urn:ietf:wg:oauth:2.0:oob kind, Google would give me an AuthCode but as soon as I put that into the form the log signaled failure:
2022-06-16 15:14:11.849 [ERROR] [oauth2client.internal.OAuthConnector] - grant type authorization_code to URL https://accounts.google.com/o/oauth2/token failed with error code redirect_uri_mismatch, description Bad Request
2022-06-16 15:14:11.858 [WARN ] [ce.googletts.internal.GoogleCloudAPI] - Error initializing Google Cloud TTS service: Error fetching access token. Invalid authcode? Please generate a new one.
I set TRACE on:
openhab> log:set TRACE org.openhab.voice.googletts openhab> log:set TRACE org.openhab.core.auth.oauth2client
and then entred a new AuthCode into the form. The log reported:

When I noticed that redirect_uri was completly different than what the UI gave me I decided to try an update and indeed there was a new oh milestone to install.
Unfortunately, while I see a change it still doesnāt work. there is a different value for the redirect_uri parameter, https://www.google.com.
Following the UIās example I can open a new tab but instead of a login screen and finally the Authcode I get an error message Error 400: redirect_uri_mismatch
I searched the google cloud console, created an additional client, later created a new project to follow the docu step by step. No change whatever I tried.
Is there a place where I would need to enter the redirect uri so it can be matched successfully?
After hours of trying I feel lost. Thanks for any input
