Impossible to setup OneDrive on CloudSync

[Dgram]

I have been trying to use cloudsync with onedrive for more than 6 months but it still doesn't work. The setup initially seems to work, logged into Microsoft Account, approved permissions at Microsoft but then it remains loading for several minutes, eventually returning an error. When I try to repeat the procedure, the same thing always happens
Thank you in advance and I hope to be able to use cloudsync as soon as possible

What version of Cloudsync do you have installed? Please upgrade to the latest version 3.1.2.

Yes, I have version 3.1.2. I also tried uninstalling cloudsync by removing all the configuration files, but the outcome is the same.

Due to the lack of detailed description at present, we are unable to accurately diagnose the issue. In order to locate and resolve the problem more precisely, you can try the following steps:

Using Browser Developer Tools:

• While attempting to establish a connection, press F12 on your keyboard to open the browser's developer tools.

• Navigate to the "Network" tab.

• Carefully observe the request and response status of all interfaces, especially the one named "wait". This will help identify any network request failures, timeouts, or error codes returned.
