Cannot access to www.metatrader5, mql5.com or www.metaquotes.net

[Tín Trần]

Hi,

Why can this IP range: 103.9.77.0/24 cannot access www.metatrader5, mql5.com or www.metaquotes.net?

All return the same error like the attached picture below.

Is it possible that IP addresses within this range are being blocked by MetaTrader? Is it possible to find out the reason why and have the ban lifted in the future?

Thank you.

I had similar issue with host file and WebVew2 and so on (on computer with Windows 10) -

So, it may be the other reason: anti-virus software, firewall (in your computer or any), and so on.

I do not know the technical details.

Because when I had similar issue so I re-installed WebVew2, and check host file in computer:

I think it may be related to host file -

• host file (website is showing something wrong): this thread https://www.mql5.com/en/forum/458988
• decision (solved): #8 and #14 and #3 

more:

• hosts file: the thread (English),
• post #3 with instruction about HowTo.

This case is definitely not due to any of the above reasons. Basic checks show that all connection attempts were terminated by the MetaTrader server.
