Search engine robots crawl your website to discover pages and then index and rank them. This is part of the ranking mechanism and is an important search engine optimisation issue. The site error as shown in the Google search console are an indicator of design of the site which can create substantial crawl issues.
The crawl issues usually arise from badly configured robot.txt file which the robots score to find out permissions. This file tells robot which page to crawl or not. In case if the configuration is wrong the whole can be out of the purview of the search engines. This will certainly show crawl error to the tune of hundred percent. Hence immediately peak into the directory in the control panel and rectify. The absence of robot.txt file means that there are no instructions and the crawler will wade through all the pages if possible.
Another reason for errors creeping are scripts that the robots are not able to decipher. This can also happen whence pages are blocked, directory is mistakenly deleted or pages simply do not exist have been mistakenly or deliberately deleted.
Low error rates would just mean the site is wrongly configured or over burdened with too many pages.
Other problems:
DNS Errors: DNS stands for domain name server where the domain is parked the DNs server is clubbed with the hosting server. Issues within this linkage may cause DNS error or some problem with the routing exists.
Server Errors: Server is the space where your site of the files and directories are hosted. There could be an error in form slow accessibility whence ther server times out. there could a breach by a virus or malware and related problems. It could also happen due a mis-configured firewall or operating systems protection. There is a mechanism to block to many server queries this can sometimes go haywire and prevent Googlebot from accessing the files. This usually happens with the dynamic URLs.
Webmasters can control how their site should be crawled usually pages with not importance are blocked.
There can be many issues the best is to visit a forum and discuss the issue if enough material is not available.
