Validation not working

kim gallagher asked on July 12, 2017 21:16

Open a page, select preview, then Validate tab, select HTML/CSS/LinkChecker/Accessibility Both HTML and Accessiblity always return this error: "Validation server is busy right now and was unable to respond in time. Please try to validate the code again.‎" Link checker reports broken links that are not broken. Kentico support claims it's our firewall. It's not. Our IT department has traced it and no problem on our end. I see this issue has been an outstanding known problem for some time. Any clues?

Since it is no one's problem, have you attempted to debug through the code to see what is happening or why it's returning false positives? You can find a good start by looking in the /CMS/CMSModules/Content/CMSDesk/Validation/Accessibility.aspx.cs and /CMS/CMSAdminControls/Validation/AccessibilityValidator.ascx.cs and a few other controls you will find once you start digging.

Have you tried any external service like Screaming Frog to help with these validations?

It's unclear what version is in use here, but this issue may have been addressed in hotfix 10.0.23:

Validators - Error when performing HTML validation of HTML5 pages

Attempting to perform HTML validation of HTML5 pages resulted in an error.
