openHAB just updated from 2.5.6-2 to 2.5.7-7 and now this binding is completely broken for me - just a warning for others who might experience this as well if you update openHAB…
Seems to be a certificate issue, identical to what is described in this community forum post for a different binding that also “broke” when openHAB was updated. Here is the full error code that now appears when I go to the Amazon Echo Control binding configuration URL, in place of where my Echo Devices and serial numbers would normally be listed:
HTTP ERROR 500
Problem accessing /amazonechocontrol/0654f2d8. Reason:

It seems one can “self-sign” the certificate but I’m not too familiar with that process… trying to figure out how to accomplish this now, or might just downgrade openHAB for now…
Edit: Sorry for false alarm, but everything seems to be working again after letting openHABian update Java from Zulu 8 OpenJDK 64-bit to Zulu 11 OpenJDK 64-bit, which is no longer in beta, according to the “openHABian Announcements” info screen. This resolved all of my Java certificate error problems and I am now running the latest openHAB stable (2.5.7-7) again with my Java error issues resolved. Perhaps this information might be helpful should anyone else experience the issues I had when openHAB updated itself.
TL;DR - Make sure you keep your Java updated. 
Edit 2: Well… never mind - the certificate error is back… 
… I’m going to just downgrade openHAB back to 2.5.6-2 for now and call it a night. Sorry for all the posts. Hopefully I’m the only person who is experiencing this issue…
…
Haha, I swear I used the search function! It seems this issue has already been discussed/reported…
