I have the Arlo VMB4540 with Pro4 cameras. I upgraded to the new or upgraded Arlo App and now my cameras are offline. The hub has a flashing amber light. I can't tell if my cameras are synced to it or not. One camera has flashing amber light on occasion. On my app, it shows the cameras offline. I have followed the instructions to sync them, but nothing is working.</P> Fri, 31 Mar 2023 17:55:31 GMT https://community.arlo.com/t5/Arlo-Pro-4/Arlo-VMB4540-offline/m-p/1908185#M8604 jodims 2023-03-31T17:55:31Z https://community.arlo.com/t5/Arlo-Pro-4/Arlo-VMB4540-offline/m-p/1908191#M8606 <BLOCKQUOTE><HR /><a href="https://community.arlo.com/t5/user/viewprofilepage/user-id/906289">@jodims</a>&nbsp;wrote:<BR /> <P>The hub has a flashing amber light.&nbsp;</P> <HR /></BLOCKQUOTE> <P>Does the base show up in your router's attached device list?</P> <P>&nbsp;</P> <P>Does the app show the base as offline (go into settings-&gt;my devices and select the base)?</P> Fri, 31 Mar 2023 18:59:38 GMT https://community.arlo.com/t5/Arlo-Pro-4/Arlo-VMB4540-offline/m-p/1908191#M8606 StephenB 2023-03-31T18:59:38Z
