R500 access point go offline and non responsive when configuring with 1100
Hello everyone, We have an issue configuring new R500 access points with a ZD1100 controller and wanted to know if anyone else has either seen this issue or has a fix.
We have a ZD1100 running version 18.104.22.168 build 11. We have tried to introduce two R500 access points and when the controller sees them it detects it joins with a different firmware/custom file version and is being upgraded. We then get a message that the AP is disconnected and we cannot communicate with the access point again.

2018/07/05 12:52:57Medium AP joins with different firmware/custom file version and is being upgraded.
Do we need to match the firmware when joining new access points before joining the controller or do we need to upgrade the firmware on the controller. I am aware this is an older controller but the R500 is supported on this firmware version.
