Fix: The Recovery Server Could Not Be Contacted – Mac OS Sierra
If you are trying to install Mac OS X (while in mac os recovery mode) onto a new volume on your Mac over your LAN network or Wi-Fi, you may receive an error.
The recovery server could not be contacted.
A solution provided by a user (Brano) on our site:
1. Launch Terminal and type:
ntpdate -u time.apple.com
Note: If you receive "operation not permitted" put sudo in front of the command.
sudo ntpdate -u time.apple.com
2. Proceed normally.
The problem is, SYSTEM DATE is wrong, and CERT validation is failing (https)
First, ensure your Mac is connected to a wired or wireless network. To connect wired network, plug an Ethernet cable in. To connect to a wireless network, go to the top right corner of the screen and choose the wireless icon and connect to a network.
If you are still experiencing the issue, it is very likely that the Apple servers are busy processing download requests for other users. You may also see your installation time rise significantly but come down suddenly over time.

Brano,

After typing ntpdate -u time.apple.com,
It returned with teo messages, Can’t find host nor servername provided
And
No servers can be used, exiting
Nothing works for me from previous comments. Whetever I do I am always downloading a 19mb installer application with the same message "The recovery server could not be contacted".
I don’t understand what should doing after Waited the command?
Worked like a charm

I did all the steps, but after it said "downloading High Sierra, etc etc etc" it stood there for more than 2-3 Hours.
Please help.
