“Not working” can mean a dead link, invalid account, blocked queue, captcha failure or temporary server error. Identify the layer before changing settings.
Check the link
Open it in a private browser window. Deleted or expired files cannot be repaired by Premium.
Check the account
Log in on the official website and verify that paid status and remaining traffic are shown.
Check JDownloader
Update the application, refresh the account, use one connection per file and test a single link.
Check browser and security tools
Disable script blockers for the test, allow cookies and remove stale site data. Security software can also interrupt large downloads.
Wait before repeated retries
Temporary file-server failures often resolve later. Rapid retries can create more errors.
