Resolution

Check and resolve any connection stability issues. If the problem persists, you can increase the number of retry attempts in the Xopero ONE application—to do this, simply edit the MaxRetriesCount parameter in config.json file, changing its default value from 2 to a higher one, such as 20.

To modify the config.json file, you must stop the Xopero ONE agent service. After making the necessary changes, restart the service and, if needed, refresh the updates in the Management Service panel.

You can edit config.json with a simple text editor (i.e., Notepad++).

The config.json file, by default, is located in the following locations:

1. For Windows: C:\Program Files\Xopero ONE Backup&Recovery Agent

2. For Linux: /opt/XoperoONEBackupAgent/
