Hello @dnakorea!

Works for me on MS-Edge. What version are you using? I may need to run latest windows update to get latest but just in case, my version reads:

- Microsoft Edge 44.19041.423.0
- Microsoft EdgeHTML 18.19041

Looking forward to your follow-up!

Hello @dnakorea!

Tried updating MS-Edge to its chromium based version here. So now I got this: Version 91.0.864.67 (Official build) (64-bit) and...

The upload worked fine in the example!..

There must be something very specific going on. Maybe you're behind a proxy? South Korea (I presume) doesn't have a "great firewall" like China, does it?

Can you clone the Ext.NET 7 Examples project (https://github.com/extnet/examples.ext.net); build, run and check if, locally, the example turns in the same error?

If the issue happens locally, you should be able to catch the actual issue or exception triggered server-side.

If not, this could be a communication issue with our servers, although I don't really see how it would block upload file requests while the others go fine. Check your browser's developer tools console for exceptions or warnings it may be firing, this could help us understand what's going on.

This may also be an issue related to how ASP.Net Core (or 5) handles file uploads. You don't get the issue if you run google chrome or other browser, do you?

Looking forward to your follow-up!

Hello again @dnakorea!

Glad you could find a solution for that. If you determine what change in the browser settings caused the problem, please share with us, maybe there is a way to counter this in the served page instead of requiring the clients not to use that (whatever it is) setting.
