I hope you can help me - I'm not technically minded so any assistance would be gratefully received!
I'm having trouble with a hub for a cat flap (https://www.surepetcare.com/en-gb/internet-hub/hub) that plugs directly into my Virgin hub by ethernet cable, and allows me to connect to it by an app on my iphone. The new hub and app won't connect, and when I tried to troubleshoot I got the following message from the makers of the hub (Sureflap)...
Thank you for your email and video. Can we please ask you to check with your internet provider that there is no firewall restriction that are blocking the ports of your router and request to open the following outbound traffic ports: HTTPS – 443 and/or MQTTS – 8883?
“Its likely a wireless problem get a better wireless router with 1Gb ports and use the hub in modem mode.” this is rubbish. The OP has said the device connects via Ethernet cable, not WiFi.
The seller of the device does not understand networking. You cannot open outgoing ports, they are ALL automatically open. 443 is HTTPS and is used for web site access and is never blocked on the incoming ports.
