# Disable external content URL

# Disable external content URL {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Manage how external link metadata is used in your instance with Connect Chat.
If the glide.ui.url.external.content system property isn't set to the recommended value of false, then Connect chat retrieves external link metadata in order to render richer content in
messages with links to Youtube, news articles, images, etc.

Ensure that the Glide Property glide.ui.url.external.content exists in the System Properties \[sys_properties\] table and is set to the value false. If the property does not appear in the
table, add a new record.
