Error message: your connection is not private

[VASCAR2]

I switched to a wireless hot spot for internet access because the buried telephone cables in my area are junk. Being in a rural area it might take a decade for Frontier to replace the cable for 25 houses. Once I started using the hot spot I am not able to get a reliable connection to this forum. I can still access this site using my iPhone. I removed all the security settings on the hot spot but still doesn’t work. I just tried to use my iPad via wifi and I still get the warning and can’t access the forum.

If I use my iPhone as a hot spot I can use my iPad to access the forum. Technology seems to be about 2 steps forward and one backwards for me.
