    Hi Raymond,

    With these results you won't be able to access our cloud service. 

    [91mnx-zh.nxvms.com:80 CLOSED
    [91mnx-zh.nxvms.com:443 CLOSED

    Especially these two lines confirm that the connection between the site and the cloud service is blocked. This could be a local network limitation, but could also be an ISP or a country blocking a service.

    Hi Raymond,

    Can you run the provided Python script on the server you are trying to connect to? 

    Please share the results with us.

    Be aware that if there is any country blocking another, there is not much we can do and you need to use the standard port forwarding method to connect to the server(s).

    Don't think this is entirely blocked in China as we can use the cloud service by 4G and some of the boardband, of course the speed is not as fast as in other places like HK (connection to server takes 45-60 seconds in average).

     

    Thanks.

    Hi Raymond,

    After several tests, it looks like there is a dead point between HongKong and China.
    We are not sure that if this is due to the networking devices/firewall/national network limitation. But likely this is a question to your ISP. They should be able to check the dead point.

    BTW, we are going to set up a cloud instance on AWS in PRC. Maybe you would get a stable connection then.
    We don't have the ETA yet, but likely would be ready by Q3/end.

    Thanks.

    Raymond,

    Based on your case we decided to add/set up our cloud infrastructure in China, so traffic never needs to leave China.

    We hope it would resolve any firewall issues. Besides, it will speed up things.

    We are actively working on this. It should be a matter of days.

    Sergey,

    This is a great news!  Even better than solving the route between China and outside as customers will have better experience with NX Cloud and NX system.

    Kindly keep me posted on when it will be online and I can help to test.

    Thanks.
