After updating to version 9.1.1 (42639) I can no longer authenticate with Google Drive

[tro2789]

Describe the bug
After updating Cyberduck, I am no longer able to connect to Google Drive. It prompts me to log in to my google account via Firefox, and then once I do, it simply loads up the oauth page again. After clicking my account a second time, it says

Connection Failed. Network is unreachable: connect. The connection attempt was rejected. The server may be down, or your network may not be properly configured.

Google drive is not currently down, as I can access via browser without issue. This also means my login credentials are not the issue, nor are Google's servers. My network is also working fine, as I'm able to use the internet and other applications are fine.

To Reproduce
Steps to reproduce the behavior:

1. Open Cyberduck
2. Click on 'Open Connection" and select Google Drive.
3. Click 'Connect'
4. Google OAuth page appears in Firefox, asking me to Choose an account. I choose an account.
5. The error message appears in Cyberduck as described above.
6. I have also tried Google Chrome and Microsoft Edge, and the issue persists across browsers.
7. I have also tried downloading Cyberduck on different PCs here at home to see if my main machine was the problem. However, the issue persists.

Expected behavior
I expect Cyberduck to successfully connect to Google Drive after logging in, as it used to do before the application was updated.

Desktop (please complete the following information):

• OS: Windows 11 24H2
• Version: OS Build 26100.2605

I have Adguard Home on my network, but the issue persists even when it is turned off. Also, like I stated previously, the issue also persists across different devices here in the home. Even on fresh installs of Cyberduck.

The strange thing is, I am able to access all google services without issue in my browser and across different devices in the home. But for some reason, Cyberduck is not connecting.

One thing I just tried on a whim is connecting to a VPN, and then attempting the connection. This was successful, so I'm wondering if it has to do with my IP. I am on a dynamic IP behind CGNAT. I wonder if API usage has been blocked the IP range that I am in for some reason. I say this because I don't have any firewall rules on the individual PCs or my router that would interfere with google services. Very strange.

The issue is that with #16639 IPv6 address may be preferred over IPv4 and no attempt is made to connect using IPv4 if an IPv6 address causes java.net.SocketException) Network is unreachable: connect. In #16723.
