I got AP11 InstantOn devices. Once connected to Site-A, It showed solid amber after setup. Same device I connect to Site-B, everything look fine and WIFI was enabled as I config. Once I bring back to Site-A, It showed solid amber again. But WIFI SSID was shown as we config on site-B too. The different between Site-A and Site-B is Site-A have Load-balance VPN Router Cisco RV320 & CISCO SG300 as following draft diagram.
AP11 --> CISCO SG300 --> CISCO RV320
Once I connect to AP11 via Browser, I got error as image below.
There are any config on RV320 will cause this error or not?
