I cannot access my hub, either through a computer or the mobile app

I have a C7 that I have been using for years. I recently went to access it and cannot - it times out when I try accessing with my computer's browser, and the mobile app shows information I assume is outdated - it shows the original IP, but the hub shows as a different IP when I run arp. I have tried accessing by IP and specifying ports 8081 or 8080. Is there a hardware reset? I cannot get in to do a soft reset, or anything else requiring menu access.

You can always start by resetting the network settings on the hub. From Network Setup | Hubitat Documentation

Network Reset

If you are accidentally blocked from accessing your hub (e.g., due to a misconfigured static IP address) or want to revert hub network settings to default for any reason:

  1. Turn the hub over and locate the recessed round button just beneath the surface of the case (pictured below).
    Hub reset button, located on bottom of hub models C-5 and later
  2. Use the point of a pen (or other small, blunt object) to press and hold this button for at least 7 seconds.
  3. Release the button, and the LED on the front of the hub will blink. The hub will begin rebooting and the LED will turn blue after a few seconds. After a few minutes, the LED should return to green, at which point the hub has finished rebooting and should again be accessible.

Thank you! I have no idea where my manual went off to, and I would not have identified that button myself.

So, all sorted and working again?

Done and dusted, many thanks!
