I have removed a subdomain from my main domain. We have stopped the subdomain completely. However the crawl still shows the error for that sub-domain. How to remove the same from crawl reports.

Earlier I had a forum as sub-domain and was mentioned in my main domain. However i have now discontinued the forum and have removed all the links and mention of the forum from my main domain.

But the crawler still shows error for the sub-domain. How to make the crawler issues clean or delete the irrelevant crawl issues. I dont have the forum now and no links at the main site, bu still shows crawl errors for the forum which doesnt exist.

Hi there

I would double check the following:
Internal links
Sitemap
Run a ScreamingFrog crawl and see if any URLs are redirecting to a subdomain page

I would also look into:
You can utilize the change of address tool through Google's Search Console
You can also request a removal through Google's Search Console.

When did you remove the subdomain? Are these Moz errors or Google Webmaster Tools errors?

Let me know - thanks so much!

Patrick's answer gives you a great check list. I'd only add that you within Moz Analytics you can customize the crawler to only report on a certain portion of the site if problems still arise in displaying your data. Still, by using 301 redirection from the old subdomain to new location, cleaning up any old referencing links, and blocking further indexation you should see the errors disappear. Cheers!
