one way to confirm a possible DNS issue would be attempting to browse to a website through it's IP - e.g. when you're unable to load any websites, try browsing to http://18.104.22.168/
- that will attempt to load Google without doing a DNS request.
If that works, we know it's a DNS issue and need to take a closer look at that.
By standard, the VPN servers tell the clients upon connection to use the OpenDNS servers (22.214.171.124 + 126.96.36.199). It's unlikely that these are blocked by your cellular ISPs - but conflicting DNS settings might be responsible.
First, let's see what connection methods you have been using - it sounds as if your connection attempts were all made via 3G/4G, so a cellular network connection? (even if tethered)
Have you been able to check if the same happens when being connected to the web via Wifi?
To investigate possible DNS problems further, possible steps would be:
- When using Wifi: In the Wifi network's advanced settings, try setting the DNS manually to OpenDNS (IPs above) in the "advanced options". If you've been setting DNS there already, try using defaults by not using advanced options at all. (examples: http://hmastuff.com/i/20140314112558644.png
Wifi DNS settings should be overridden by the VPN servers settings anyway, but if the default settings are the cause of the problem, this would be a way to confirm it.
- Wifi/3G/4G: With apps like "ROM toolbox" or others (search on GooglePlay for "set dns") you can attempt to manually set your default DNS settings for either cellular or Wifi networks. In most cases though that will require a rooted device.
It would also be interesting to know if you're having similar trouble with the other Android based VPN connection methods ( https://support.hidemyass.com/forums/23007608-Android-General-
) - e.g. PPTP, L2TP, OpenVPN Connect, FeatVPN.
This will show us if the situation is caused by the HMA! app, or your network situation/settings.
You can also provide us with additional info that might help us pinpointing or recreating your issue:
- What device are you using the HMA! Android app on?
- What Android version is installed? (Settings -> About phone)
- Is your device rooted?
- Are you using the stock firmware, or a custom ROM?
