If the bot has never run on your wiki before, it is possible the bot is not yet configured for it. If you leave a message on our talk page we can work on setting up the bot for your wiki. Also, when a bot is enabled on a wiki for the first time, it can take potentially days for the first edit to be made.
If the bot has run on your wiki before, it is possible that the bot has been disabled server-side. When this happens, it is because there is a bug that is preventing InternetArchiveBot from working effectively on that wiki. Please wait for service to return to that wiki. Also check to make sure the bot is not blocked on your wiki.
