## AI overview

This troubleshooting article explains that Android users receiving ERR_TUNNEL_CONNECTION_FAILED when accessing HTTPS sites over Airtel mobile data may be affected by the Airtel Live access point's proxy. Clearing the proxy and port settings resolved the problem.

## Source excerpt

For the past few days, whenever I tried to access any site with HTTPS, I used to get this error. "This webpage is not available ERR_TUNNEL_CONNECTION_FAILED" This used to occur only on mobile network (airtel) and not on WiFi. At first it seemed to be a problem with chrome. But the same problem was there in other browsers. After breaking my head for a while I read somewhere that android doesn't support SSL over any port other than 443 (too weird to be true). But this couldn't be the issue because https://google.com , https://twitter.com etc use 443. Upon investigating further, I realized that it is a very silly issue. It is because the default Access Point (Airtel Live) that came with my carrier (airtel) had a proxy that was not allowing SSL Tunneling. After setting Proxy and Port to nothing, the problem was solved!
