Object Upload or Download Errors

Scenario 1

Symptom

During object upload or download, error "ERR_NAME_NOT_RESOLVED" is displayed, indicating that the server's IP address cannot be found.

Solution

Configure the local hosts file by referring to Configuring the Local hosts File.

The local hosts file should be configured in the [OBS backend IP address] [Bucket domain name] format. An example is given as follows:

xx.xx.xx.xx bucket-name.obsv3.example-region.com

In this example:

[OBS backend IP address] indicates the value of obsv3_address provided in the "1.1 Basic Parameters" sheet of the parameter summary file exported during OBS installation.

[Bucket domain name] can be found on the bucket's basic information page on the console.

After the configuration is complete, refresh the page and message "Your connection isn't private" may be displayed. For more information, see Scenario 3.

Scenario 2

Symptom

During object upload or download, error "ERR_CONNECTION_TIMED_OUT" is displayed, indicating that the connection timed out.

Solution

Check whether the local hosts file is incorrectly configured by referring to Configuring the Local hosts File, or check whether the IP address is correct and network connectivity is normal.

To check the IP address, do as follows:

Open a new browser window and enter the bucket domain name (an address starting with https://). Then, the browser should display a warning that your connection is not private.

Skip the warning. If the XML messages are displayed, the IP address is correct. If the messages are of any other type, further check whether the IP address is correct.

Scenario 3

Symptom

During object upload or download, error "NET::ERR_CERT_AUTHORITY_INVALID" is displayed, indicating a privacy error.

Solution

This happens because OBS has no commercial certificate and cannot be trusted by the browser. The workaround for this problem is to click Advanced at the bottom of the page and click "Continue to XXX".

To completely resolve this problem, download and install the OBS certificate. When installing the certificate, select Place all certificates in the following store (Trusted Root Certification Authorities).
