# Disable external content URL

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.
