Have a T1500G-10PS network switch that I am trying to add to Omana cloud controller. I have added 2 APs sucessfully but cannot get the switch to even connect. The status page on the switch reports as offline. I have tried with and without the Omada inform URL but the result is the same. Switch has internett access and can ping external servcers (tested Google and CloudFlare and both are working, also NTP is working). I have also tried with the IP address instead of the URL for the inform URL, but didnt make a difference.
