Dear Hirwan,
I'm Renzo, I'll help you with your question.
In order to verify your cloud storage, in any internet browser on incognito mode (Ctrl+Shift+N) go to below link and access with your personal account:
https://onedrive.live.com/?v=managestorage
If you are able to access it and your problem is local, I mean, if the problem it's with OneDrive client at your PC, you could try with following process:
1. You can try with an OneDrive Reset, so take a look at following process on the link:
https://support.microsoft.com/en-us/office/rese...
2. If previous process does not works, you could re-install OneDrive client with following process;
Do you know how work with the "Regedit"?
3. So, with the keys combinations (Windows + R), you'll open the "Run" windows, then type: regedit
We need to find OneDrive folder and delete it.
you will find it in this path:
HKEY_CURRENT_USER\Software\Microsoft\OneDrive
Expand Microsoft folder click on the "arrow", inside you'll see the OneDrive folder, click with "Right-Click" over OneDrive folder and delete all.
This process only remove OneDrive configuration, the data will be fine.
Take a look more information in following support:

4. Next, uninstall OneDrive client from Control Panel and re-install again, you can download it from following link:
https://support.office.com/en-us/article/onedri...
Download the last "Production Ring" version and install it.
5. Open the app and sign in, then when you select the folder location for OneDrive (use default folder), maybe will appears a message that says "This folder already has information/data", so, in the same way, select that location and accept.
Note: By other hand, if you are not able to open it on the browser, could be due to a temporary service degradation, normally this degradation take no more than 72h to be solve it.
