Temat: Samsung phone/tablet site problems when on hotspot

It only happens when using my ATT Unite hotspot. Certain sites get "site unavailable" or "server DNS address culd not be found.' Only happens when using hotspot. Have used this hotspot with another android phone and these sites come in without problem. When on home wifi all these sites come in without problem. Other sites come in, but some seem to be blocked.
These are not adult or restricted sites. they are business sites and blogs.

Please help.

Thanks!

I didn't find the right solution from the Internet.
