I could see the problem is the fault of the mobile operators in Venezuela, specifically Movistar.

I tried to connect to a VPN on my Android Device and the UDP and TCP ports are blocked. Maybe that's what produces the connection error. I could connect to a VPN using ICMP and Opera Mini works.

I will communicate with Movistar but I do not think they do anything to solve it.

In the desktop PC using a ADSL connection
works Opera Turbo, I will try later SurfVPN.

Thank you for your help @mbaluta, If Opera Team can do something to fix this I'd appreciate it.

1. Venezuela
2. Movistar - Telefónica Venezuela
3. I'm using mobile internet (away) and ADSL at home.

I tried on 4 phones using Movistar as the operator and 3 show connection failure.
Friends using Digitel 4G (another mobile operator) have no connection failures.

Thanks for your help.

Opera Mini for Android is not connected to internet problem Servers Opera, the problem happens in Opera 7.6.4, Opera Mini 12 and Mini Opera 13 Beta 2.

The problem also occurs in Opera Browser for Windows 8.1 when Turbo Mode is activated the connection is lost.

I'm using Opera for over 7 years ago and it makes me uncomfortable having to use another browser, please resolve this connection error

Sorry for my English

How to reproduce the error?

1. Open opera mini 8 beta 7 or any previous beta.
2. Try to load any web page or open a saved page

Expected Result:
View and surf over any website.

Result obtained:
Website loaded but the browser only shows a blank page.
Thumbnail image window manager shows the
page as charged.

I report this error since beta 1 has occurred in a galaxy portal (with cyanogenmod), galaxy ace duos (rom stock) and a htc one s (AOSP rom).
The Htc One S now and not this error occurs after the beta 3 or 4.
I no longer have access to galaxy ace, so I can not test whether the bug has been fixed in the latest betas.

PD: I did not speak English and use Google Translate for this. I hope all is well translated and they can understand, if something senseless or something messy, sorry.

Opera does not load any website. Even the saved pages imported from Opera Mini Stable.

Sorry for my english

Continues without to show the content of the pages loaded. Any web site loads like a blank page.
I reported this error since Beta 1 and still has not been solved.

Sorry for my bad english.

The bug 'ANDEUR-83162' has not been
corrected in this version. The browser does
not show the content of the pages loaded.
