Greetings
It's possible that the blank screen you are seeing when accessing the URL provided in the AWS solution for accessing files within your Elastic File System using a simple file manager created with CloudFormation is due to authentication issues.
Here are a few things you can try to troubleshoot the issue:
Check your security group settings: Ensure that your security group settings allow traffic on the necessary ports for the file manager to communicate with your Elastic File System. By default, the file manager uses port 80 for HTTP traffic and port 2049 for NFS traffic.
Check your network settings: Make sure that your network settings allow traffic between the file manager and your Elastic File System. If you are using Amazon VPC, ensure that your VPC configuration allows traffic on the necessary ports.
Check your IAM roles and permissions: Ensure that your IAM roles and permissions allow you to access the necessary resources, including the Elastic File System and the file manager.
Check the CloudFormation stack outputs: Check the outputs section of your CloudFormation stack to see if there are any errors or warnings that may indicate issues with the file manager setup.
Try accessing the file manager from a different browser or network: If you are still unable to access the file manager, try accessing it from a different browser or network to rule out any local network or browser issues.
If none of these troubleshooting steps work, you may need to review the AWS solution documentation and make sure that you followed all the steps correctly.
