Invicti Standard, Invicti Enterprise On-Premises, Invicti Enterprise On-Demand

Launching, running, and finishing scans in Invicti Enterprise can sometimes end with errors.

These errors may occur due to various reasons, such as issues with the target URL, authentication, proxy, etc.
Such errors can prevent you from completing essential scanning tasks, leading to delays, and missing vital information to identify and fix vulnerabilities.
Having an understanding of the common scan error messages and their causes can help you resolve these issues and keep your scanner functioning smoothly.

This topic lists the common scan error messages and provides helpful tips to assist you in resolving them effectively.

Note: Scans marked as failed or canceled will be automatically deleted 90 days after their status changes. This applies to both Acunetix 360 On-Premises and Acunetix 360 cloud versions.
