So I come across this error when trying to upload a file from c: to different places. Like installing firmware on to network units or uploads file to some places. However it goes fine when upload files to Facebook ore google error reporting.  I tried Chrome and Internet Exporer with same results. 

This is what happens in the logs

The window where you should be able to choose the file you want to upload goes blanks and then the explorer hungs. Tried to search arround for a fix, no luck so fare. Could it be a problem after an update. I found out that this has worked on other clients i my domain with similar setup before. 

Hi Knut W,

When did the issue start to occur ? Did the issue only occur in this specific machine ?

Please ensure the machine has got the latest updates and all the updates have been installed correctly(View update history).

We can take the following step to have a troubleshoot :
1.Perform a clean boot to verify whether there is a third party conflict here.

2.Run "sfc /scannow"and "dism /online /cleanup-image /restorehealth" to check the health of the system .

3.If the issue occured recently,we can perform a system restore to recover the machine to a previous point to have a check .

Best regards

Hi

Sorry for long answering time on this one.

Finally been able to to do some more research about this error. We tried to install a new pc with the same specs and updates  as the other pc , but with the same result. Still hungs when trying to reach file Explorer from web Application. With the same errors as mentioned before.

Knut

Hi knut,

"Still hungs when trying to reach file Explorer from web Application" "We tried to install a new pc with the same specs and updates  as the other pc "
Do you mean you have performed a clean installation in this machine ?
Do you mean the issue will occur when we try to reach the files explorer from the specific web application or all the web applications ? Did the issue only occur with the specific machine or all the machines ?
If it only occurred with the specific web application ,it is recommended to look for help from the web application developer for help .

If it only occurred with the specific machine ,have you tried to perform a clean boot to have a check ?

Have you tried to copy files to a network location from the Windows Explorer to have a check ?

Best regards
