Is that IP address the IP address of the same hub you're using to perform the update? If so, try port 8080 (an alternate for the default port 80 that should serve the exact same content), so http://yourHubIP:8080/local/fileName.otz for the firmware file in the updater driver.
Alternatively, are you on a C-7 hub? If so, you could try the new(-ish) built-in firmware updater app as an alternative to using the driver. This takes care of the file upload for you and also works a bit differently, though I'm not sure if there are any differences at the Z-Wave level (the UI is the biggest notable difference), so if everything else is correct in your setup, I can't guarantee that this would work differently. It also won't work if you're on a C-5 or earlier, even though it will let you install the app.
It’s been awhile since I used the driver version of the updater, but I’m not sure it works correctly with a securely paired device such as a lock. I believe I had to pair without security to do updates to my Aeotec devices, and, certainly, the Alfred lock would normally be securely paired.
Bryan Copeland (@bcopeland), who wrote the driver, would know. I don’t believe he has been maintaining the driver version since he joined Hubitat staff and wrote the built-in app version that only works on the C-7.
I have another C5 hub I use for testing, so I have that next to the lock and I paired the lock, install the driver and upload the firmware to the file manager and started the process over again. I turned off the battery saving mode in Alfred to allow the app and the door to always communicate which will keep it from going to sleep, but that didn't work either.
I sent Alfred an email to see if there's a way to get this firmware updated outside of Hubitat, so I will see what they say, but if the answer is NO, is there anything else I can do other than getting a C7 just to update a firmware?
Well, there is. Get a Z-Wave USB stick, use PC Controller, which is a part of SiLabs free Simplicity Studio. PC Controller can update OTA firmware very quickly.
