Unable to load file from Open File

[Takuya]

I am using a Mac. I tried to load a PDF file from the Open File in the SfPdfViewerServer component, but I get the "Attempting to reconnect to the server: 1 of 8" and the file does not load. How can I solve this problem?

I have published the program I use on GitHub.

The following is my environment.

- .NET 6.0.400

- Visual Studio for Mac 17.4 Preview

Thanks for the reply. I added AddHubOptions and the message display is gone, but it is still loading and will not proceed. I uploaded the video below. I have attached a pdf file of the actual test.

I have looked at the Network tab and don't see any errors, and I don't see any errors in Visual Studio either.

I have tried disabling Chrome extensions and antivirus software but no change.

Thanks for the confirmation. I do not know the cause of the problem, but it seems that the problem is only in my environment. I was able to display the PDF without any problem on my Windows PC, so I will proceed with the development there.
