Generic x86 - GitHub

I have been struggling with access to GitHub from a Generic x86 install on which I am running HA on an SSD. This is what I see when I run ping from Terminal.

In case I had done something stupid at the system level I made a fresh SD card using these instructions and set the BIOS to boot from the SD card first. I then set the user to Advanced Mode and installed Terminal. As you can see from the screenshot below, I did not install any other add-ons. I get the same result: I can ping other websites, but not GitHub.

Are there some other settings that I am missing? I cannot see anything in the instructions?

I’d really appreciate a quick response because I need some HACS updates.

Here is the raw system health report for the original install on the SSD.

Can you ping github from another device using the same internet connection?

Yes, from any other device connected the the same network.
