Aruba Instant IAP205 access points not synchronising configuration

I have an installation of 5 x IAP205s. They have all gone through the initial configuration, have discovered each other and all are visible from the GUI presented by the virtual controller. However, when I make a configuration change from the GUI it does not replicate to two of the five access points (the configuration delta from the "show delta" command doesn't change to the new version shown by the VC). And error messages like those below are shown in the log of the VC.

The software on all the APs has been updated to the latest version via the GUI and the "show version" command on all APs show:

Re: Aruba Instant IAP205 access points not synchronising configuration

HI,

 

This issue generally occurs when there is any IP reachablity . check whether those IAPs are able to reach the Master and as a work around try to restart those two APs

 

Please feel free for any further help on this.

Cheers,
Venu Puduchery,
