[2017.1.0p4] Unity Bug Reporter doesn't work.

In 2017.1.0p4 (64bit) on macOS 10.12.6, I want to report a bug by using Unity Bug Reporter but the reporter has been always stopped while uploading the report. Cancel button does work, but doesn’t progress the uploading every time.

Does it need any kind of port forwarding?
Or it doesn’t accept a report from Japan???(jk

How can I do report a bug?

I’ve succeeded reporting from my own PC at home.

The reporting took too much long time despite I use a dedicated 1Gbps line.

An above post was posted from an office in a wi-fi network.
So now I’m guessing that was just a super long delay of the network.
