AP and WLC are connected to each other through VPN, and they are sufficiently joined so that they can be used.
However, after the VPN is disconnected, the AP is disconnected from the WLC, and when the VPN is reconnected, the AP cannot rejoin the WLC.
However, if you reboot the AP, it joins the WLC well.
I have no idea why the AP is not automatically re-joined to the WLC.
Couldn't it be possible to automatically join the AP without rebooting it?

- This may also depend on the type of VPN-solution that is in place (vendor and or architecture). Probably in this case vpn-connections may need to get authenticated again 'after a break' (for instance).

Is wireless only traffic effected or any other traffic also ?
do a capture on inside interface on FW on AP side and see if you see capwap traffic, then do capture on inside interface on FW on WLC to see if the traffic is getting across tunnel, also look at encap and decap packets count change while testing this.
start with this and let us know, what you find.
hope this helps

1. Yes it should re-connect automatically.
2. Do as @ammahend suggests.
3. Also get the console logs from the AP after the VPN failure to see what the AP is doing?
4. What version of software is the WLC running?
5. Is the AP using static IP or DHCP? What discovery method is it using for finding the WLC?
