Arlo Pro base station requires ports 80, 123, 443 to be open. If you have a router from your ISP, there's a chance these or one of these ports has been closed for security reasons. You may need to contact your ISP to ensure these ports are open for your Arlo to work</P> Sun, 23 Jul 2017 22:35:13 GMT steve_t 2017-07-23T22:35:13Z https://community.arlo.com/t5/Arlo-Pro/Base-Station-connection-issues/m-p/1328522#M17996 Hi,<BR />Arlo base station describes model# VMB4000<BR />Initially when I bought I don't have connection issues. When I set up the new modem and router and connecting to Arlo base, orange light keep blinking but never connects. I tried reset the base station, I believe Reset button is not working.<BR />Please suggest on how to proceed.
