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.

Sorry but I still cannot get rid of the error, I am connected via Ethernet and Wifi and ran the Sudo command several times... I have tried deleting and formatting my HD but the error still happens.
any other ideas
This worked perfectly the first time
THANK YOU!!! This worked for me!
I'm still not having any luck after trying the steps mentioned. Still it reads: The recovery server could not be contacted.
Please help!
Hi, I have tried this a few times now, without success. I am trying to reinstall from Recovery Mode. And always still get the same message. Any more ideas how to crack this? Thanks
thank you this help solve my problem. first I was receiving an issue but it was due to not being connected to my Wifi. thank you for the help.
you are such a savior!
I did the terminal reset thing a bunch of times, and still no luck. I also did the hosts suggestion, and still getting the error message.
I needed to run the terminal command three or four times but it finally updated and it works a treat. Thanks!
Brano,
If I could kiss you I would!
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.
I get a [-bash-3.2# when I open Terminal. What is that?
Completed all the above steps and nothing works, but i didn't complete one on deleting file bc i never got the message that step suggested
what i did and it finally worked
1. did the terminal thing which you can find by searching it in the right search bar (did it about 5 times)
2. clicked on the internet symbol and clicked the WIFI name about 3 times
3. checked back on the update and it finally let me through to the terms and conditions page!
probably just luck but maybe just try it out just in case. It might work you never know.
Good luck everyone!
Adjusting time did not work for me. I've been working with Apple support for 4 weeks. He is now suggesting I back up my Mac and we wipe it clean and reinstall the OS.
After entering the terminal command, it asks for password...?
