Server errors are fairly rare but can be difficult to fix without an IT professional. As servers don’t report what error occurred to an external party, you’ll need to examine your servers’ logs to get more information about the error. Feel free to reach out to our support team if you need assistance with identifying crawl times.
If you’re interested in learning about what different server errors indicate, this site has a helpful guide to common errors.
