There are some reasons due to which it occurs such as loss of internet, server downtime, DNS resolution issue or some trouble in the installation files.

Reason behind this error
During recovery or reinstallation the macOS is attempting to connect to the Apple server but for some reasons it can’t be contacted. The reasons to explore are as follows:
- The macOS is not given access to the internet.
- The Apple server is not reachable or overloaded.

Solution of Recovery server could not be contacted error
Since the reasons of this error are known, therefore the solutions are self-explanatory. However, we shall provide a step by step guide to troubleshoot this error in a systematic. fashion.
Check internet connection
Your primary concern should be the internet connection. Make sure that the same connection is working on another device. Sometimes the internet connection is not working at the providers end and this can be the root of the problem.
During the recovery, in the status bar simply connect your Wi-Fi.
Check server’s status
Apple’s servers can’t be the culprit because of their huge infrastructure but sometimes when new updates are rolled out the servers get overloaded. Therefore, it’s important to check the status of the Apple’s server by visiting this webpage.
Check system’s time and date
Another specific reason for the recovery server contact rejection can be the date and time mismatch. The date and time of the system should match with that of the server and in that case just check the current time and make sure it matches with that of the system.
You can also launch terminal during the recovery and run the following command:
ntpdate -u time.apple.com
Alternatively, if that doesn’t work use following:
sntp -sS time.apple.com
