Website has been operational for years. Getting normal amounts of traffic from the normal areas. I am currently in the Maldives trying to admin a few things and the SG CF rays cannot contact my webserver - getting 521, unreachable.
Origin server is on VPS and no limiting http/https firewalls.
My IP in Maldives is: 123.176.22.xxx and I can SSH/HTTP/HTTPS with no problem to my webserver. Seems the SG ray isn’t able to connect. Again, no HTTP/HTTPS firewalls - everything is setup to direct via https:// which is functioning normally from my office in the USA.
