We can override default portlet is temporarily unavailable error message by overriding the portlet_error.jsp file.
By default that error message is coming from
/html/portal/portlet_error.jsp file
Override that jsp file using hooks.
Replace that code with the below code and change error message as required
<%@ include file="/html/portal/init.jsp" %>
<div class="alert alert-error">
Unable to process your request.
</div>
