How can I solve the "i/o timeout" error during the initial setup of CubeBackup?
If you encounter an HTTP connection timeout error during the initial configuration of CubeBackup (like the message above), this means your server failed to connect to the Google OAuth service. The most likely cause of this error is that your backup server is behind a proxy server, and the proxy settings have not been added to the CubeBackup configuration file.
To allow CubeBackup to communicate with Google services via a proxy server, please follow the instructions below:
Step 1. Open the configuration file config.toml, and add HttpProxy=“http://<proxy-server-ip>:port” as the first line.
For example, the config.toml should look like this:
HttpProxy="http://192.168.1.100:8080" [Web] Bind=":80"
Starting with version 4.7, the configuration file is located at <installation directory>/etc/config.toml for fresh installations of CubeBackup. For installations upgraded through the console, or versions prior to 4.7, the configuration file is still located at <installation directory>/bin/config.toml.
On Windows, the default installation directory is located at c:\Program Files\CubeBackup4.
On Linux, the default installation directory is located at /opt/cubebackup.
Step 2. Restart the CubeBackup Service
sudo /opt/cubebackup/bin/cbsrv restart
Enter services.msc in the command line, and in the Services list that pops up, right click the CubeBackup Service entry, then select Restart.
sudo docker restart
If the connection problem persists after the above operations, you can:
- Contact your proxy server administrator to make sure Google services are not blocked by your proxy. Detailed instructions can be found at https://support.google.com/a/answer/2589954?hl=en
