How to resolve Possible outages issue ?
It can be a transit issue, you may had been working on some migration maintenance work when the bots tried to crawl your website. Just try visiting the pages mentioned in the error message through a web browser. If they exists then try getting it fetched from the Fetch as Google option.
If you cannot see these pages on a browser, then check the header type by using websites like webconfs.com to analyse the http header code. If it is a 404 return then its for sure that the page does not exists on your hosted environment.
