iphone/ipad cannot connect printer

[plebe 3]

Hi Folks, 

1. UM3+ connected to LAN via Wifi. Works great. Printing many jobs over network.

2. Cura app on both Mac and PC connect to printer just fine. I can manage printer and see camera stream via Cura AND web browser.

3. Apps on both iphone and iPad find the printer just fine. Clicking on the printer in the list on either device produces error: Can't connect to *my printer name* Your iPhone is connected to "Wi-Fi".   

4. Verified the IP address of printer is within local device DHCP range of IP's.

5. Verified the iPhone and iPad are also within DHCP range of IP's. 

6. Re-installed iPhone app and still not giving me access, though I can see the printer in the list and as mentioned, can click on it. 

 

I recently updated firmware after not printing for many months. Machine asked to be updated so I did. Running latest Cura 4.8.x.  Unit has been powered off and on several times.

Ideas where to start looking? I'm getting a great stream off LAN computers, but want to check in on print progress without visiting printer (within wifi range, not over internet).

Thanks in advance...
