"Network Failure" message in AWS Resource Groups Console page

The "Network Failure" message you're seeing in the AWS Resource Group console typically indicates that there was an issue with fetching data from the AWS services or APIs associated with the resources in your saved resource group. This could be due to various reasons, including network connectivity issues, service disruptions, or throttling of API requests.

Could you please do the below checks:-

Since you mentioned that the affected resource group differs in terms of tags applied to the resources, review the tags applied to the resources within the group. Ensure that the tags are correctly formatted and do not contain any invalid characters or values that could cause issues.

Ensure that your network connection is stable and that there are no issues with internet connectivity. You can try accessing other AWS services or websites to confirm that your network connection is working properly.

Check the AWS Service Health Dashboard (https://health.aws.amazon.com/) to see if there are any ongoing issues or outages with the AWS services that your resources depend on. If there are any service disruptions, you may need to wait for AWS to resolve them.

The real reason is its a problem with the browser "Brave". The same issue is not produced in other browsers (Chrome, Safari, Firefox). Also the issue arises only when creating the resource group with the key word "Google-Analytics" in the "Brave" browser.
