Before we continue, please ensure that:

Your iPhone’s plan includes tethering, meaning your carrier supports Personal Hotspot. If you are not sure, contact your carrier to verify that your wireless plan supports this. If Personal Hotspot is dimmed or unavailable, go to Settings > Cellular and make sure that Cellular Data is turned on.
You log into the same Apple Account on your iPhone and your Mac.
You enable Wi-Fi and Bluetooth on your iPhone and your Mac. On your iPhone, go to Settings > Wi-Fi, then go to Settings > Bluetooth. On your Mac, click the Wi-Fi status menu in the menu bar, then click the Bluetooth status menu in Control Center.
Your iPhone and your Mac are within 30 feet (10 meters) of each other.
If you use a VPN on either device, make sure its configuration doesn’t prevent local networking. Apple lists this among the things to check for Instant Hotspot, noting that it may interfere with some Continuity features.

On your Mac, choose Apple menu > System Settings, then click Network in the sidebar. Control-click Wi-Fi, then choose Make Service Inactive. Now Wi-Fi will be inactive. Now Control-click Wi-Fi and choose Make Service Active. If you are still unable to connect, then select Bluetooth and follow the same steps: First, make it “Inactive” and then revert back.
If your Mac still won’t connect, try Maximize Compatibility on your iPhone: go to Settings > Personal Hotspot and turn on Maximize Compatibility. Apple notes that Maximize Compatibility may reduce performance for devices connected to your Personal Hotspot when turned on.
