While the AP is showing online there must be some AP to SZ communication issue as the configuration has not been received and acknowledged by the AP (New Configuration means the configuration update to the AP is pending).
The AP support info file is downloaded from the SZ GUI by highlighting the AP then selecting "Download support" from the more pull down in the menu bar above (this is from an vSZ-H, it may be different on SZ-100):
In the example above it is greyed out because the AP is offline.
If there is a communication issue from AP to SZ then the support log may not be retrievable from the SZ gui ... but give it a try.
There could be lots of reasons why the AP is not getting the configuration. Network/firewall ACL issues, AP operational issues or code problems. Diagnosing this via the Forums is probably not possible.
