Capwap State DTLS teardown (no console, no web page)

[zununah]

Hi. I recently mounted two CBW140AC-B AP. 
First one took three hours to "get" the ip, it was blinking green-red-orange. This means 

"Stage — 7 IP assigned and Capwap Init (If a Primary AP exists in network moves to stage 8 else switchdriver process starts)".

After those three hours, I was able to access to the web page (please tell me if WLC is the same that the web page?). Note that during all the whole time, WLan was working fine, my laptop could get a proper IP in every time.

Then I mounted the second AP, I have waited three days to see if it gets the ip, but it did not. It was blinking green-red-orange too and I was not even able to ping the static IP.  After that, I assigned an IP in another VLAN, this time I could ping the IP, but I am not able to access the to the web page. Again, Wlan is working fine.

So I connected a console cable to the second AP using putty, and it shows this:

So the AP is pinging, its detecting my first AP (for now the first AP is working fine) but I am not able to access to the web page or login into the console because I need to enable it from the web page. Thanks for your help

Most of us here have never worked with the Small Business product range and they are not documented in as much detail as the enterprise products so we can only offer generic answers.

Before going any further make sure you have the latest firmware installed on all the APs:
https://software.cisco.com/download/home/286324956/type/286325362/release/10.9.1.0
You might need to unplug the primary to get access to the second one.
I know it says the other APs will update from the primary but they won't if they can't connect like yours so best to update them all manually so that you know have the same firmware version on them all.
After they're updated you might be better off doing a factory default reset on all of them to make sure you start with a clean setup.  https://www.cisco.com/c/en/us/support/smb/product-support/small-business/wireless-mesh-100-200-series.html but if they all just work then great!
