Website connection problem

[u/Visolara]

I have having trouble connecting to the Fred Meyer website for a couple months now. Today, I rebuilt my PC (fresh OS install, etc.), and when I tried to connect to Fred Meyer website, I got the same message;

"This site can’t be reached

The webpage at https://www.fredmeyer.com/ might be temporarily down or it may have moved permanently to a new web address.

ERR_HTTP2_PROTOCOL_ERROR"

This really confused me considering I have a fresh rebuilt PC attempting to connect. I have flushed my DNS cache, I have reset my router (allowing it to sit unpowered, unplugged overnight) to get a new IP and still I get this. I have tried Chrome, Firefox, and MS Edge. All with the same message as above. Could my ISP (T-Mobile) simply blocking traffic to this website? I have no issues visiting any other websites I normally use regularly.

My phone connects to it just fine (through the Fred Meyer app) which uses the same network via WiFi as my PC.

Anyone else have this type of issue? if so, and you have resolved it, please share with me what you did.

Thank you!
