Alexander Keilhofer 0 Posted February 21 Share Posted February 21 Hi, We are using Endpoint Security with WebControl to block certain pages. When the client is connected directly it works just fine. When the client is using a web-proxy (but is able to resolv DNS etc. directly) blocking a https-site works, but the Browser displays "ERR_TUNNEL_CONNECTION_FAILED" Blocking HTTP-Sites works by displaying the configured site. According to this page we are not alone - yet no fix works. Setting "Use Proxy" in Eset does not help either. TL:DR: Blocking HTTPS sites works, but does not display a nice site.

Administrators Marcos 4,919 Posted February 21 Administrators Share Posted February 21 Can endpoints communicate with ESET's Web Control servers listed in https://support.eset.com/en/kb332 on UDP port 53535? If only communication via the proxy server is possible, an HTTP tunnel to avcloud.e5.sk:53535 must be allowed. Link to comment Share on other sites More sharing options...
Alexander Keilhofer 0 Posted February 21 Author Share Posted February 21 Hi, the client can communicate without any firewall in between. The „block“ works- but the site is not injected. Instead, the connection is just reset. Link to comment Share on other sites More sharing options...
