YouTube API Connection Verification Failure

Hello, everyone,

This is my first time posting, and I have read and tried the current proposed solutions, none of which have worked so far. I have been using my YouTube module for months now with no issues. I am using three different accounts, and ONE of these three has recently started requiring that I verify every hour or so. The other two modules are working fine as usual without any need to connect using the secret key and Client ID. The only change to this specific account that I have made recently is adding Google Site Kit to my WordPress site and getting evaluated for adding ads to my account.

Here is the error I get:

Error

Failed to verify connection ‘ColorBlockHome Design’. Status Code Error: 400

  • - Failed to verify connection ‘ColorBlockHome Design’. Status Code Error: 400”

Error

Cannot initialize the scenario because of the reason ‘Failed to verify connection ‘ColorBlockHome Design’. Status Code Error: 400’

  • - Failed to verify connection ‘ColorBlockHome Design’. Status Code Error: 400”

I have added signing in with secret key and client secret, and the issue persists. Has anyone tried anything else that works?

Here are the previously shared solutions I already tried:

Please help me!

Doesn’t help but I am having the exact same error. I can reauthorize the connection but an hour later it doesn’t work anymore.
