GSC Performance completely dropped off, but Google Analytics is steady. Why can't GSC track my site anymore?

Hey everyone!

I'm having a weird issue that I've never experienced before. For one of my clients, GSC has a complete drop-off in the Performance section. All of the data shows that everything fell flat, or almost completely flat.

But in Google Analytics, we have steady results. No huge drop-off in traffic, etc.

Do any of you know why GSC would all of a sudden be unable to crawl our site? Or track this data?

Let me know what you think! 
Thanks!

I would check the Index Coverage report in GSC, and then maybe try re-submitting your sitemap in GSC.

For Google Analytics I would check under the Source/Medium report to see if Organic Google traffic has changed at all.

Hi

Check the Google Search Console forums, to see if there is a bug or delay in reporting data. Sometimes the data falls flat and will be restored within a few days.
