Harmony crashes HASS

Hello.
A couple of days ago my HASS stop working (no web gui, no reactions). By turning off plugins in configuration.yaml I figured out that it was caused by Logitech Harmony. I use Harmony hub, here is part of my configuration.yaml:

remote:
  - platform: harmony
    name: room
    host: 10.0.1.20

IP is right one, previously this setup worked well. No significant changes were made, I received one update for Hub, but seems like HASS stoped working 1-2 days after Harmony update (what maybe means that update is not the reason) and I updated OS as well.
I use Hassbian on RPi3, with latest updates and Harmony Hub 4.12.36.
They are in same subnet.
I see no errors in HASS log, only this:

WARNING (MainThread) [homeassistant.setup] Setup of remote is taking over 10 seconds.
WARNING (MainThread) [homeassistant.components.remote] Setup of platform harmony is taking over 10 seconds.

Harmony conf file doesn’t been created, HASS not accessible (no web gui). Without Harmony section everything work.
Did anyone else faced with this issue?

My fault.
Hub’s IP address wasn’t static, so one day it got another IP address, but HASS tried to connect old one.
Hope my topic will help anybody with same issue.

Btw.
And I think that when HASS is not able to connect something, it should give an error on webgui/log/etc. But in my case it just crashes, so figuring out what wrong is a little bit difficult.
