since upgrading to 0.46 a few hours ago, I’m starting to see proxy errors behind my Apache reverse proxy (again):
[Sun Jun 04 17:52:12.388205 2017] [proxy_http:error] [pid 62231] (20014)Internal error: [client 192.168.x.x:64287] AH01102: error reading status line from remote server 127.0.0.1:8123
[Sun Jun 04 17:52:12.388298 2017] [proxy:error] [pid 62231] [client 192.168.x.x:64287] AH00898: Error reading from remote server returned by /
On the frontend side I get 502 errors (not 504 as last time) - not that it makes a difference…
My config didn’t change in ages and it worked fine since HA switched to aiohttp 2 end of March.
Until 0.46 today…

I added keepalive=on to the ProxyPass directives and the 502 errors went away. However, starting on the hour, I start getting constant 401 errors about my cameras. Logging out of the HA web UI and back in again makes the errors stop but then they return at :00 on the next hour.
