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
I have attached a photo of the problem

After laboratory verification, the cloud drive connection is normal. To facilitate identifying the issue you are encountering, we need you to confirm the following:

1.Please ensure that your device is properly connected to the internet.
2.Please open the console using F12, and after authorizing the cloud drive connection, observe the content returned by the "wait" interface.
3.If the above steps do not resolve your issue, you can contact our online customer service through the official website, and we will arrange for an engineer to assist you remotely. Note that when contacting customer service, please send a screenshot of this post to the customer service personnel.

I hope that you can found a solution.

I'm sorry, but I couldn't obtain the relevant information from the screenshot you provided. You can follow the image information presented below and perform the corresponding operations in sequence, especially points ③ and ④.

Thank you very much for your time.
these are the screens of your request. the screen remains blank all the time until it gives an error. The strange thing is that I tried adding dropbox and it works. I'm really going crazy because that's why I got the nas.
