    it should work but lock may not show green and secure; that is expected. If you can't get to secure sites, please use http://dave.thehorners.com/. If your ISP has restrictions to certain sites, consider another provider or another VPN. Life is too short and precious to be controlled and manipulated.

What's your locale like? I hope it's not oppressive. See here, a beautiful view from satellite(s) below. God Speed; and Good Luck.


    Ppl of the Internet. Right now, dave.thehorners.com is unavailable on the *[LTE AT&T network] (outage has been persistent for a long while; last personal report to ATT with no response 11/11/2018)

    I don' t know if it is an outage or what; but please do a tracert from your device and request access to dave.thehorners.com if it doesn't route from your ISP (at this time I only KNOW that LTE ATT is affected if you find otherwise, please post proof in deepdream. I was told 24 hours; but that was days and days ago. I would be interested in the help...frustrating figuring out a routing|sensor|censor problem.
