Home Assistant 24h Periodic Freeze

Hi. I am running Home Assistant 0.111.4 on a raspberry pi. I have several esp32 LoRa modules that transmit to a ESP32 LoRa to MQTT gateway. The gateway then puplished MQTT to HA. For some reason every morning at 4am the gateway stops publishing to Home Assistant. I correct the issue by rebooting the power on the gateway and everything runs fine again. The only clue I have is the error message below. Unfortunitly this does not mean anything to me, and was hoping anyone could shed some light on what might be causing my issue.

2020-06-26 04:01:19 WARNING (zeroconf-ServiceBrowser__axis-video._tcp.local.-_printer._tcp.local.-_ipps._tcp.local.-_api._udp.local.-_elg._tcp.local.-_googlecast._tcp.local.-_wled._tcp.local.-_viziocast._tcp.local.-_spotify-connect._tcp.local.-_daap._tcp.local.-_hap._tcp.local.-_ipp._tcp.local.-_miio._udp.local.-_esphomelib._tcp.local.-_dkapi._tcp.local._2894266400) [zeroconf] Error sending through socket 16

This is the result on my graphs:

Thanks in advance!

Looks like your gateway is disconnecting from the network at 4am for some reason.

Before restarting it next time see if you can ping it.
