what is that Proxy? and how to remove that without using any VPNs?
It may just be your ISP. Many ISP's use proxies because they have more subscribers then available IP's. They count on a certain percentage of them being off line most of the time.
The IP address you listed, 184.108.40.206, is assigned to an organization in the Maldives, Cablenet JSAT, as you can see by doing a whois lookup through whatismyip.com. You can tell it is in the Maldives even without doing a whois query because the fully qualified domain name(FQDN), cache1.satlink.mv, which is associated with the name ends in "mv", which is the country code assigned by the International Organization for Standardizaton (ISO) to the Maldives, an island nation in the Indian Ocean. You can see a list of all the two-character country codes assigned by the ISO here.
Satlink.mv indicates the address is assigned to SatLink, a wireless Internet Service Provider (ISP) and cable TV provider in the Maldives.
As Shnerdly mentions, your ISP or your company, if you saw that while at work, may be using a proxy server for web traffic. Another reason proxy servers are sometimes used is for security; the proxy server can block access to sites deemed inappropriate or dangerous.
If you saw the message while browsing the web at home, it is even possible that your home firewall or router has been configured to route traffic through a proxy server for that security purpose. Or an antivirus, parental control, or other program installed on the system you used when that message was displayed could be configured to use a proxy server to ensure safe web browsing. If you were on a home system, you could check other home systems, if any are available, to see if they, too, route web traffic through the proxy server. If they aren't you may want to investigate the software on the one system that routes traffic through the proxy server to determine what application is doing so.
