We keep getting a crawl error when trying to use SEMRush and other audit tools to check our site for issues and errors. I’ve checked our codes and our robots.txt and nothing is being blocked and I’ve allowed the SEMRush bots crawl access. The site will crawl in some online tools, but with others we get errors like “URL is invalid” and in SEMRush we continue to get a crawl error due to a “server error” however we can’t find anything wrong on our end. Any insight as to what the issue may be?
