Please provide your hub model (C7, C8, etc.) and its platform version from Settings>Hub Details.
Cannot connect to my C8 hub through my iPhone app. I have a iPhone 14 Pro Max on iOS 26.1
The hub is Ethernet connected and can only be accessed via its URL.
So the issue appears to be that your hub can’t reach the cloud (aka the internet), according to your last screenshot.
Have you tried rebooting the hub?
Can you describe how your home network is setup in more detail? What kind of router? Is the hub connected directly to the router by Ethernet or is there a switch in between?
What are the multiple online troubleshooting options that you have tried?
FYI you don’t need to obscure your hub’s local IP address when posting screenshots publicly. Even with the last octet revealed, the information is meaningless to everyone else on the internet. My hub’s at 192.168.1.49. There is nothing that anyone here can do with that information to compromise my hub’s security.
However, your second screenshot contains your HUB ID and MAC address. You should redact both of those pieces of information from your screenshot so no one else can see them.
To confirm, you are on iOS 26.1 (beta), and not 26.0.1 (current prod)?
If on iOS 26.1 beta, then perhaps this thread may be useful...
It looks like Hubitat 501 did have Internet access on September 19. Can you confirm that your C8 has been working normally up until that date?
Did you make any changes to your home network, or make changes to the Hubitat on that date?
Is your Hubitat connected by WiFi or Ethernet? Are you using a static IP, or are you using a DHCP assigned IP?
Is your 15 BrinstoneBridge hub on the same LAN as Hubitat 501?
26.1 should not be an issue. I am running it on an iPhone and iPad without issue.
The C-8 was working through my phone app up until 9/19. It’s connected directly to the network (Verizon router) via Ethernet through a PoE+ network switch. Other devices connected to the switch are working without issue.
No static IP (I believe it is assigned).
There haven’t been any network changes.
The other hub is at a different location and works fine through the app.
I have rebooted the hub, disconnected the hub from everything, waited 5 minutes then reconnected. I have deleted the app and reinstalled.
Connected to a Verizon router through a PoE+ switch..
With help from Grok, these are the troubleshooting steps I tried…
• This is the #1 fix: Unplug the power for 30 seconds, then plug back in. Wait 2-3 minutes for the LED to go solid green.
• Why? It forces a fresh connection attempt to the cloud servers, resolving transient drops even if your internet and network test pass.
• Test after: Check the dashboard status or try the Hubitat app remotely.
• Once rebooted, go to Settings > Reboot > Run Network Test in the web interface. Look for “Internet” and “Cloud” to both show as connected.
• Also, under Settings > Hub Details, ensure the “Hub Time” is current (if not, click “Update from browser time”). Out-of-sync clocks can disrupt cloud pings.
• In Settings > Network, confirm it’s set to DHCP (not static IP) unless you have a router reservation. If static, switch to DHCP temporarily.
• Do a network reset: Press and hold the reset button on the hub’s bottom with a paperclip for 7-10 seconds (LED flashes rapidly), then release and reboot. This refreshes the IP lease without a full factory reset.
• On your router: Log in and check for IP conflicts or ensure the hub’s MAC has a DHCP reservation. Also, set your router’s DNS to reliable public ones like 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)—DNS glitches are a frequent culprit.
• In Settings > Hub Details, look for updates. Recent firmwares (e.g., around 2.3.9.x) have caused daily cloud drops for some users; rolling back or updating might help if it’s version-specific.
• If no update shows (due to cloud block), you can sideload via local file upload once connected—grab the latest from Hubitat’s site on another device.
• Temporarily disable any router firewall, VPN, or security software (e.g., Pi-hole) that might block outbound traffic to service.cloud.hubitat.com or api.hubitat.com.
• Test internet from the hub: In the network test, ping external sites like google.com to confirm outbound access.
In your reply to @marktheknife you listed a number of troubleshooting steps that were recommend by Grok. Are you saying that you completed everyone of those steps, and each of them passed?
I would say that if you reset the Hubitat's network settings, by pressing the hidden button on the bottom, then you are using a DHCP assigned address. This would imply that the IP, gateway and netmask values are all correct. However, you could change the Hubitat to a static IP, to ensure that the correct gateway and netmask for your network are entered. This would be especially important if your network has a netmask other than 255.255.255.0
Since you have access to the Hubitat from the local LAN, then the problem must be in the router or switch.
Is this a "managed" switch?. Can you plug the Hubitat directly into the router temporarily, even if that means bringing the Hubitat to a different location, and see if that resolves the problem.?
Do you have any type of parental controls enabled on the router? .
Can you try connecting via Wi-Fi to verify if that works?
“Since you have access to the Hubitat from the local LAN, then the problem must be in the router or switch.
I bypassed the switch and connected directly to the router via Ethernet, still no cloud connection.

The switch is not managed

No Parental Controls

Wifi will not connect to my C-8 on my local network
Sorry I missed your prior reply to me.
Is the hub’s last check-in still showing as 9/19/25?
Do you mean that you can access the hub from a web browser running on a device connected to your home network? What URL did you enter into the web browser? Did you try connecting by using the IP address?
Does your connection via the app fail only when you are away from home (The app says "Cloud"), or also when you are at home at connected by Wi-Fi (The app says "Local"). Does the app actually say "Local" when you are at home?.
I suggested trying to connect by Wi-Fi to rule out any potential problems with the ethernet connection. Can you explain what you mean by your reply?. Your hub refuses to connect to the Wi-Fi, or when it does connect to Wi-Fi, the hub is no longer accessible on your local network.
“Is the hub’s last check-in still showing as 9/19/25?“ YES
The hub will not connect to wifi
Tagging @support_team.
Grok is hallucinating on this one: "sideload via local file upload." That is not possible.
Unfortunately, there isn't much we can do remotely to troubleshoot cloud connectivity issues. One thing to check, if you didn't already, is the "Hub Time" on Hub Details page. Worth updating from browser and waiting for a few hours to see if the hub connects to the cloud.
Also, since your hub is running a beta version prior to 2.4.3 public release, I would try restoring the 2.4.2 version to see if that fixes the problem. Version 2.4.3.120 was available in beta for just one day (Sept 18th - Sept 19th) and had some networking enhancements, which may be the culprit for your issue. The timing between the update and the problem you are facing are suspiciously close, which suggests the two might be related.
