External No Response
What This Means
External URLs with no response returned from the server. Usually due to a malformed URL, connection timeout, connection error, or connection refused.
What Triggers This Issue
This issue is triggered when an external URL responds with a status code 0, such as a connection timeout, connection error, connection refused or DNS lookup failed.
How To Fix
Malformed URLs often respond with ‘DNS Lookup Failed’ and won’t resolve at all in a browser. They should be updated to the correct location. Other connection issues should be checked in a browser, as they might be due to security identifying the SEO Spider request as a bot. They can often be ignored or resolved by using different user-agents (‘Config > User-Agent’), adjusting the crawl speed (‘Config > Speed’), disabling firewalls & proxies or adding your IP address to security platform allowlists.
