How to Fix Joomla Extension Updates Not Appearing
Confirm Joomla update support
Run Find Updates under System → Update → Extensions. Joomla help notes that only extensions supporting Joomla's update system are listed.
Check Update Sites
Confirm the extension's source exists, is enabled, and points to the expected provider.
Clear stale information
Use Clear Cache on Extensions: Update, then Find Updates.
Check connectivity
DNS, TLS, outbound firewall/proxy rules, redirects, HTTP errors, or vendor outages can stop Joomla from retrieving update XML.
Check compatibility filters
Update metadata can restrict Joomla platform, minimum PHP, and supported database versions, so a newer release may not apply to the current site.
Check identity fields
For developer-level diagnosis, element, type, plugin folder, and client where required must match the installed extension.
Separate download-key problems
A commercial download key may affect package retrieval even when update discovery succeeds. Distinguish a missing update from a listed update that will not download.
Verify with the vendor
Confirm the current supported release and update method, then run Find Updates again after correcting the source or environment.
