My VPS cannot connect to jenkins.io and its Mirrors

[M Fachmi Rizal]

Greetings , 
I tried to install jenkins in my new VPS from Contabo.. but when executing "sudo apt-get install jenkins" it said cannot connect to the jenkins mirror and failed... when I test to ping the jenkins.io from terminal using "ping -v jenkins.io" it doesnt return anything.. 

but in my other VPS and local computer, installing jenkins and ping jenkins.io work flawlessly...

today i tried to install jenkins manually from deb file and it work.. but I cannot install the plugin because it says it cannot connect to the server..
I tried to contact the customer service, but they can't help because this is technical issue.
Please help me, I also attach the images
Sorry for my bad english..

Thanks,

Rizal

Their network firewall rules seem to block traffic to the nearest Jenkins mirror, at Tsinghua University in China.  You'll need to work with your network provider to fix their network firewall rules.

It’s basically a network or connectivity issue, most corporate Linux systems  are Customized repos which are not allowed to connect out of the box repos or urls as default. Either way you would need to to communicate this with your system admin and network admins for a bypass if this are POCs or if you are on a prod you would have to raise a request to your admins.

Thank you @all for your responses..
I ended up with offline installation for jenkins plugin... because my VPS vendor cannot fullfill my requirement,, It's clearly network /  connectivity issue.
