Q Light Controller+

Another update: Solved!
viewtopic.php?f=7&t=13646

Update!
I have narrowed it down to Apple/Safari/OSX/iOS issues and how OSX Safari and iOS handle communication with port 9999. Seems inbound communication from RPI on that port is blocked by Apple. Researching.

Chrome and Waterfox on OSX devices work well. Safari does not.
On iOS, neither Safari nor Chrome operate (I assume port 9999 is problematic at a lower level in the os...)
Android devices (Chrome) works fine.

Is Apple being overprotective?
Can another port other than 9999 be used?

-------------------------
OP...

Making progress. Created scenes and virtual console buttons QLC+ on MAC, everything fine.
Loaded .qxw file on Raspberry Pi, use Chrome on MAC Mojave 10.14.6 to log on and run on Pi. Everything fine.
Shut down MAC, connect via Android tablet. Everything works as expected.
Shut down Andriod, and connect via iPad Pro running IOS 12.3.1, open Chrome browser,
I log on using name & pw, then get QLC+ Connection Error! hit OK then QLC+ connection lost!
Choice of OK or Suppress Dialogs. Either choice shows Virtual Console, but is more or less dead.
Same on older iPad running IOS 9.3.6.
iPads work on everything else flawlessly, only have errors w/Pi running Masimos QLC+ image unmodified.
MAC and PI hardwired to router.
Android and iPads via WiFi.

Any ideas?

Something new:
MAC connecting via WiFi and Safari presenting the same problems as iPads.
MAC connecting via WiFi using Chrome or Waterfox running properly.

Maybe something with port issues on Safari and IOS devices.

So, let me ask another way:

Is there anyone using iPad to connect via websockets to the QLC+ app on Raspberry Pi using stock, unchanged image by Masimo?

Please just give me a yes or no (I've seen some using TouchOSC running on iPad, but that's not using the browser...)

From what I'm finding on the web, my belief is that Safari has either blocked, or more likely needs another "piece" to get websockets working - not a port 9999 issue.

Of course, I may be on the wrong track. An online test confirms websockets enabled.

WebSocket supported here!

Version/12.1.2 Safari/605.1.15

test by jimbergman.net (based on Google sample code)

Similar message when same test performed with iPhone SE.

Ah HA!
A different online test gave somewhat different results:

With Safari browser: Some immediate disconnects. One wonders...
Of note, the tests do not test port 9999, rather some other standardized ports.

This test was created to study implications of using WebSockets in real-life scenarios. Having WebSockets supported in your browser doesn't guarantee they will work for you. Antiviruses, firewalls and HTTP proxies may interfere WebSocket connections, sometimes rendering them useless.

On this page you can see how well WebSockets can work with your Internet Connection, your Antivirus and all other software you have. The test checks WebSocket operation by connecting to the WebSocket-enabled server and exchanging the data. The time displayed in "Server time" line should update every second if WebSockets work for you.

This server supports WebSocket Protocol proposed standard (RFC-6455, December 2011), per-frame-deflate-extension-00 draft, older websocket drafts as well as even older Hixie drafts 75 and 76 (August 2010) with the fix for HTTP reverse proxies.
