Cannot detect nodes with ipmi

Hello!

I am currently using MAAS Version 1.9.5+bzr4599-0ubuntu1 with Ubuntu 14.04.5, with three nodes (all Dell PowerEdge R710). I am currently trying to use IPMI version 2.0.

However, I am unable to power-up these nodes with Maas, due to an error:
Failed to query node's BMC - Power state could not be queried: 10.1.10.134: connection timeout

In /var/log/maas/maas.log, an identical error message appears.

I have double checked the BMC configuration for these nodes, and they seem to be correct (I can provide screenshots if necessary), however, I am still unable to communicate with these servers using IPMI. (eg. ipmipower, ipmiping, etc. all do not work.) and I am not sure what else I can do. If anybody could help me or point me in the right direction, I would very much appreciate it!

If there's any more useful information that I can provide, please let me know.
