Not able to submit IC3 report

I have gotten messages like this five times when I try to submit my report to the IC3 from different browsers, networks, and incognito. What is wrong and what can I do?

Hmmm... can't reach this page

It looks like complaint.ic3.gov closed the connection.

Try:

+ Checking the connection

= Checking the proxy and the firewall

ERR_COMNMECTION_CLOSED

Check your Internet connection

Check your network cables, modem, and routers.

Allow Microsoft Edge to access the network in your firewall or antivirus settings.

If it's already listed as a program allowed to access the network, try removing it from the list. and adding it again.

If you use a proxy server:

Go to the Microsoft Edge menu > Settings > System > Open your computer's proxy settings > LAN Settings and

deselect the "Use a proxy server for your LAN" checkbox.
