Strange WHM & cPanel Access Issue

[Albatross0403]

I cannot access WHM or any cPanel on my new laptop. I even tried from AMP and tried Root Access. I can access all of it just fine from any other computer/device on my network, both hard lined and WIFI. I turned off my firewall & virus protection and that didn't help. I've tried from Chrome and got this message:
This page isn’t working
server.my_domain.com didn’t send any data.

ERR_EMPTY_RESPONSE

It also gets an error message using Microsoft Edge. I can access the websites and WP, just not WHM/cPanels. I even tried a host file mod to no avail.

Please help me figure out what I have to do to fix this.

Hello,

My Assumption would be that you don't have an A record in place for the hostname, none the less does the issue persist if you navigate to cPanel/WHM by one of the following alternate methods?

https://IPADDRESS:2087

https://domain.tld:2087

¿Has probado con un simple ping?
es posible que su nueva computadora portátil tenga algunos dns predefinidos que están generando problemas

I tried both of these (with my info):
https://IPADDRESS:2087
https://domain.tld:2087
and niether worked.

I pinged the IP and it worked fine:
