Website Connection Issue After OS Update

I am attempting to use PACER, which is the federal court database. On Monday, I upgraded my Mac to MacOS Big Sur 11.2.3. Immediately after doing so, I was unable to use PACER. When I log in, I can do a search, but when I click on a case, I get a message saying Safari can't open the page because the server unexpectedly dropped the connection. I also tried Firefox but got a message saying the secure connection failed. I've posted screenshots of both messages below. This is the first time I've ever had any issue. I use Qustodio, which is uses a VPN. Any suggestions on how to fix this? I really need to access PACER for my job, and I don't have an IT expert. Any help would be appreciated!

MacBook Pro 13″, macOS 11.2

Do you have a Time Machine backup to Restore to/from?

Or get rid of the VPN...

Make a New Location to use without VPN, Using network locations in Mac OS X ...

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.

If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.

System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
