Google Drive Trigger Not Consistently Firing for Multiple Files in Hostinger server

I’m running n8n on a Hostinger server, and I’m using the Google Drive Trigger node to watch a folder for new or updated files (fileCreated or fileUpdated).

However, when I upload multiple files at once, the trigger only fires once, instead of firing for each individual file. Additionally, when I test the workflow, it consistently returns the same file, rather than detecting the other newly added files.
