# Manual patch upload connection reset Last Updated On: 04 Sep 2026 A Cloud manual patch upload can fail with **net::ERR_CONNECTION_RESET** even when the vendor package is valid. ## Cause The browser connection to the upload host is reset before the file upload completes. The package itself can still be valid. A common upload host is `https://upload-accl.zoho.in`. ## Resolution 1. Allow the upload host through the proxy, firewall, and SSL inspection. 2. Retry the upload in an incognito window or a different browser. 3. Retry from another network to rule out local network restrictions. ## Related - [Attention Required](https://www.manageengine.com/products/desktop-central/help/patch-management/attention-required.html) - [Troubleshooting patch deployment errors](https://www.manageengine.com/products/desktop-central/help/patch-management/patch-deployment-troubleshooting.html)
