Can't access Octoprint on iPhone 11

I have Octopi set up and running on a Raspberry Pi 4. It's connected to a Prusa Mini+. It's working just fine and I can access it from 3 different PCs, 2 are connected to WiFi and one Ethernet. I can connect to it on my daughters iPhone 6 and 7, but I can't connect to it from my or my wife's iPhone 11s.

I've tried from both Octopi.local and the IP Address, with the same results - it says "Safari could not open the page because the server stopped responding". I also tried it on this phone through Chrome and Octopod, with not luck.

The Pi and the iPhone 11s are both on the same network, both connected to 5Ghz. These phones aren't connecting trhough a VPN, proxy or anything else.

Any suggestions on what might be causing the issue?

Check the wifi ip of the iphones. Maybe your router puts the 5ghz devices in to an other network :man_shrugging:
