Unable to take the GUI of F5 BIG IP instance on AWS

Please include some more details on your configuration. Are you using a VPN and is the 443 allowed for the security group applied to BIG-IP's network? Are you using a single route table or have north south networks?

Without knowing further, this does work if the AWS instance is setup to allow BIG-IP's mgmt port 443 in/out to your network (NEVER use 0.0.0.0).

A secondary recommendation would be to always use an Amazon Workspace jump box for management of AWS resources like BIG-IP GUI (this is what I do). For the rest of the community, if you can please provide more detail on the network config of BIG-IP and AWS without compromising your infrastructure.

I changed the port from 433 to 8443 and it works
