## The problem
<!-- 
  Describe the issue you are experiencing here to communicate to the

Alexa.CameraStreamController in Alexa was working on FireTV for non-443 port (using Haaska) prior to upgrading to 0.110.
Starting in HA release 0.110, I now get Alexa on FireTV saying "_camera name_ doesn't support that".
As of 0.116.4 this problem still exists.  A potential fix for this is described below.

Note1: This problem was originally reported in 0.108 and later fixed to support non-443 ports:

Note2: The fix became undone in 0.110 and was reported in the following issue, which was closed and balloob had requested to re-open as a new issue.

## Additional information
I have tracked this down to the following code snippets in the Alexa component/module for the files entities.py and handlers.py
```
        try:
            network.get_url(
                self.hass,
                allow_internal=False,
                allow_ip=False,
                require_ssl=True,
                require_standard_port=True,
            )
```
By changing the `require_standard_port = False` in entities.py and handlers.py, the problem is fixed, and I can stream successfully to my FireTV.

 Comments: 
 Comment 0: The problem is that not all devices support a non-standard port (e.g., the echo show is one of them). 
 Comment 1: Hey there @home-assistant/cloud, @ochlocracy, mind taking a look at this issue as its been labeled with an integration (`alexa`) you are listed as a [codeowner](https://github.com/home-assistant/core/blob/dev/CODEOWNERS#L25) for? Thanks!

 Comment 2: If `require_standard_port=False` could a device like echo show continue to use 443 and work?
 Comment 3: As of 2020.12.0, still not fixed.
 Comment 4: I would also like to see a fix and use a different port than 443.
Maybe it would be a solution to move this property to the configuration.yaml (standard: true)?
 Comment 5: There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates.
Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍
This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.
