Why Cannot I Open the Dashboard of the Application Pre-installed in the Application Image?
Symptom
On the FlexusL console, when you click Access in the Dashboard row in the Image area, the dashboard cannot be opened.
Possible Causes and Solutions
Refer to the following to troubleshoot the fault. If the fault persists, submit a service ticket.
- The port for accessing the dashboard is not allowed in the inbound rules of the security group.
Verify that the inbound rules of the security group allow traffic over the port for accessing the dashboard. For details, see Configuring Security Group Rules for a FlexusL Instance.
Required inbound ports for accessing the dashboard vary depending on the application image. Allow the required ports by referring to the security group configuration in the best practices for your specific application image.
- The image application has not been up and running.
- Other causes
If you use a Portainer application image to create, reinstall, or change the OS of a FlexusL instance, Portainer initialization has a certain validity period. If no users are created within the validity period, a message in the following figure is displayed. In this case, log in to the FlexusL instance server and run sudo docker restart portainer to restart Portainer, and then create a user as soon as possible.
