Hello! Windows 11 22H2 22621.1555 + Thunderbird 102.10.1 (64-bit) I face a problem with Yandex mailbox with the following authentication settings: smtp.yandex.com:465 SSL/TLS OAuth2 The "Enter credentials" window gives --- 400 redirect_uri does not match the Callback URL defined for the client --- after logging into account. The address in the window is https://oauth.yandex.com/authorize?response_type=code&client_id=...&redirect_uri=http%3A%2F%2Flocalhost&scope=mail%3Aimap_full I removed the client_id but "localhost" is authentic and suspicious. What can cause the problem?

If it doesn't work with OAuth2, try 'normal password' authentication with an app password.
