The BT download server (download.bt.cn) might be down or blocking a ton of IPs.
I can ping this site using my LTE network, but not with my normal ethernet connection. It doesn't respond with multiple providers.
If you check the URL here: https://www.uptrends.com/nl/tools/uptime
You can see that a lot of countries do not get a reply.

Pinging the server ip ( 45.32.116.160 ) has the same issue.

I can't change my NGINX version now.

Is this something you can fix?

    I have a similar problem in installation but i don't know why. Maybe blocks my IP or BT Server is down?

      aaPanel_Jose Now works fine! Maybe was a network error from the company which i have the server.

        aaPanel_Jose I'm in the Netherlands, but a pinging server from Amsterdam does seem to get a response.

        EDIT: It appears to be fixed now. It was probably just some downtime.

            hello,
            DNS always set 8.8.8.8 and issues come from your server. The network & resource Vultr not stable as DigitalOcean (DO). you should try the VM in DO with Singapore location.

                If you want to enjoy the ultimate experience of Vultr server then I will recommend you to go with Cloudways. As, it provides the managed Vultr server which. Which allows you to enjoy the unbroken hosting experience. Moreover, you will avail the 24/7 support which is always busy in ensuring the unbroken up-time of the server.

                    Well i will rather go with the hosting companey itself as clouldways charge way more than the original price.I myself own a linode and vultr account(plus i paid for it) and i would just say cloudways is just taking extra money from you.
