Also update additional information, the “browser” button can work , I did not tried it before. But the “connect” will fail with the pop error message. So the login in information should be correct.

Dear r91085,

Based on the log file, it appears that some libraries may be missing from your system. Here is the relevant section from the log:

We have tested NetDrive3 on a clean installation of Windows 10, and confirmed that it includes all necessary libraries for mounting remote storage, such as pCloud. To ensure that all required libraries are installed, please uninstall NetDrive and then delete the “Bdrive” folder and all it’s contents. And reinstall it.

Regards

[r91085]

I uninstalled it and removed all NetDrive3 folder then reinstall, but the issue still exist.

The existing profile seems is sync from my another device because I can not create new profile in this mechine ( can not save profile due to the error )

But like I said before, I can “browse the cloud device content” by the browse button. So it seems the permission of accessing the cloud is good, just can not mount as disk.

And this is not only the pcloud issue, I got the same issue in other type cloud ( I only have google drive )

Dear r91085,

SSL Error 35 typically indicates that there is a problem with the SSL/TLS handshake, and it can have various causes. Some possible reasons for this error include:

1. Certificate validation failure: The client may reject the server’s certificate if it is expired, self-signed, or issued by an untrusted certificate authority.
2. Invalid or mismatched encryption algorithms: The client and server may fail to agree on a common encryption algorithm to be used for the secure connection.
3. Network connectivity issues: There could be network problems, such as firewall restrictions, that prevent the client and server from establishing a secure connection.
4. Proxy or firewall interference: Intermediate proxies or firewalls can sometimes interfere with the SSL/TLS handshake process, causing errors.

When we install the recent NetDrive version in a clean Windows 10 it works without error. So the number 1 and 2 is not the problem I think. Do you use proxy or firewall?

Regards

[r91085]

I don’t have any firewall / proxy / antivious in my device and the device has external static ip address to connect to internet directly.

I was wondering :

1. Why it could already browser the content in the cloud ( browse button, and I can upload file in that ), but can not mount ? If the device has some network issue, does it still can browse the cloud content ?

2. Why the browser say it is already linked successfully, can close the browser and it does created link in the cloud ( can see the netdrive has permission in gdrive, pcloud web interface), but actually it fail in the handshake ?

3. Some profiles was created on this mechine before (under previous version), and it worked normally before. I have disable netdrive for a while and update it recently. If my profies were created in previous version, does it cause any problem ? Or if there is something not clean totally in previous version installation ?

By the way, I have try testing in official google drive mount software and RaiDriv in this device. And it seems both of them don’t have this problem on the machine.

Dear r91085,

NetDrive’s FileBrowser feature and the Mount feature, which works through the Connect button, work differently. If the FileBrowser function works but the Mount function does not, it means that there is no problem with the NetDrive protocol.
If so, it’s a system issue, but I’ve tested on multiple devices and the Mount feature is working fine.
You can find out by reviewing the logs. The log says that the system library was not found: “error:80000002:system library::No such file or directory”
We’ve had this issue before, and the customer resolved it by doing a clean install of NetDrive3.
Would you like to try this?

1. Check your current version by selecting ABOUT in NetDrive3.
2. Install the current version you found.(Previous versions can be downloaded from this page. Change Log)
3. Restart your computer.
4. Uninstall NetDrive from the Windows Control Panel.
5. Delete the folder in the path below.
   C:\Program Files (x86)\Bdrive
   C:\ProgramData\NetDrive3
6. Install the desired version of NetDrive (3.17.960).

My guess is that this issue was caused by not being able to do a clean uninstall when you updated NetDrive.

Please let me know if you continue to experience the problem.

Regards

[r91085]

My device also have some NetDrive2 folders left (already uninstalled), besides try installing old version then uninstalling, do I need to remove these NetDrive2 folders ?

Thanks

[r91085]

I tried to install old version (3.17.799, 3.16.667,3.17.900) and follow the flow :

1. install
2. restart
3. uninstall
4. delete
5. install ( 3.17.960 )

The problem still there ( 3.17.960 ), but (3.17.799, 3.16.667,3.17.900) can work without error message.

When install old version, even I just reinstall without uninstall existing version, they still work well. I definitely remove all NetDrive related folders after uninstalling then install 3.17.960, but it still got the same error.

I feel it may not related to something in the old NetDrive related folders. I saw a change in 3.17.900 is about
“Windows: Updated Visual Studio Redistributables for optimal compatibility.”

Is it possible that this change casue this probelm ?

[tsjeong]

Dear r91085,

That makes sense, and we’ll take another look at what might be causing the issue.
Thanks for the feedback.
