Cloud Sync doesn't work on Windows OS

Xing

Cloud sync doesn't work. It says my internet access is blocked. Diarium was downloaded from Microsoft Store. To reproduce the bug: Click on Sync -> Click on Google Drive (or any other cloud services) -> The error page attached shows up. I am sure my internet works - only this app doesn't work. I tried removing and adding Diarium from accessing the network through Windows Security -> Firewall & network protection -> Allow an app through firewall, but this didn't work. I also tried disabling all firewalls on my laptop altogether, but this didn't work either. There is no Diarium update on Microsoft Store either.

Diarium version: 2.9.84.0
OS + version: Windows 11
Device model: Surface Pro 7

What you see is the error page of the browser window that Diarium shows in order for your to log into your Cloud account and authorize Diarium (for the Google sync, the URL is https://accounts.google.com/o/oauth2/v2/auth + some parameters). There's nothing I can do to fix it, it is a network problem. Please try to restart your PC and make sure there is no problem connecting to the Google servers (e.g. in your main browser). You can use the URL above to test the connection.
It is also possible that the country you are currently located in blocks connections to Google servers

Thank you for your reply. I don’t think I can fix it on my end and I still suspect it’s an app bug. There are a couple of things that made me think this:

There must be something that blocks internet access specifically for the Diarium app then. I am not able to reproduce the problem and I haven't heard about it from other users. Really don't know how I could help. All Diarium does it opening a dialog with a WebView2, navigating to the authorization URL of the Cloud Service selected.
The site in your (second) screenshot looks fine, the error is expected as it misses the additional parameters (response_type etc.) that Diarium does append in the source code. However it is not "the exact same error that showed up in my Diarium app". Your two screenshots show different errors
