Moodle error/could not upgrade OAuth token | Fixed

If you have been coming across the following error message, you have come to the right place.

Could not upgrade OAuth token

According to our experts, this error usually occurs when there is an issue with the authentication process.

Additionally, the error also pops up when the Moodle site cannot upgrade the OAuth token for a user.

This error also prevents users from accessing some features or functionalities that require OAuth authentication.

Let’s take a look at some of the causes and fixes for this error:

• This error may be due to incorrect or expired OAuth credentials. These credentials are used by Moodle to authenticate with an external service like Google, Microsoft, etc.
• In some cases, network or connectivity problems can interfere with the OAuth token upgrade process. So, we have to make sure the Moodle server has proper network connectivity and can establish connections with the external OAuth provider.
• Furthermore, incorrect configuration of the OAuth settings in Moodle can also lead to this error. In this scenario, verify that the OAuth configuration in Moodle matches the requirements of the external authentication provider.
• Sometimes, certain issues with the server environment can also lead to problems with OAuth token upgrades. So, we have to ensure that the server meets the minimum requirements for running Moodle.
• Additionally, if we are using an external OAuth provider we have to check the configuration of that service. In other words, make sure the settings, like redirect URIs or authorized domains, are correctly configured to match the Moodle installation.

In short, the following troubleshooting tips will help us resolve the error:

• Double-check OAuth credentials and settings in Moodle.
• Verify the network connectivity between the Moodle server and the OAuth provider.
• Review the server environment and make sure it meets the requirements.
• Check the configuration of the external OAuth service.
• Clear Moodle caches and try again.
• Enable detailed debugging in Moodle to get more specific error messages.
