Automatically reopen an issue?

GitLab documentation explains how to automatically:

Is there a way to automatically reopen an issue once it has been closed?

In our use-case we would like to track a connection to a network service provider who is tagged in a single issue, and reopen the issue when the service is no longer required.

I am not quite sure what you mean by automatic here. What is the input event that you envision performing the reopen of a closed issue?
