Hi @XiiChan - Since the same computer is being used on both connections, and it works on the cellular data connection but not your home WiFi router, there may be an issue with a router setting. One way to check this easily is to use a wired connection to your laptop instead of connecting via the WiFi.
Try an Ethernet (cable) connection on the home network and see if it works that way.
If you can access it via a wired connection but not over the WiFi, try power cycling your ENTIRE network.
- Turn off all connected devices (wired and wireless)
- Turn off the modem (cable/dsl/gateway) and the router. If your modem has a battery backup, remove the battery and shut the modem down completely
- Turn on the modem first. Let it completely boot up and make its connection with the ISP before you touch anything else
- Turn on the router after the modem is completely booted. Let it make its connection with the modem and wait until it's fully booted
- Turn on your laptop - again, let the device fully boot up, then connect to the WiFi network and try again
- Turn on the other connected devices on your network and let them reconnect
If you're comfortable with admin on your router you should check MAC address filtering rules, and be sure your laptop's MAC address is not being blocked by any routing rules.
Please let us know if the complete network power cycling works, or if you see any changes.
