Hi all, I keep losing access to the webui (ERR_CONNECTION_REFUSED), all dockers and SSH. A hard reboot will restore all of this but then access will be lost again after a few hours or a day (no apparent consistency). Most recently access was randomly restored without a reboot before going down again a few hours later. 

The server responds to pings and I can still access shares via SMB. I can still access some docker containers like Plex externally (i.e. via app.plex.tv) so this would suggest a local network problem. The server has a static IP assigned by the router that is outside the DHCP range. The router is a Zyxel DX3301-T0 supplied by the ISP.

Unraid is the latest stable version and was recently rebuilt on a new USB stick after another network problem where unraid couldn't reach the internet.

Enable the syslog server and post that after a crash.

I enabled the syslog client service and set it up to send logs to my windows laptop. They weren't being received but this didn't seem surprising in the circumstances but just to test I also enabled the syslog client service on my router and pointed that at the laptop too. Those weren't received either which didn't make sense. Got me to thinking that it's the laptop with an issue not the unraid machine and I tried to access the webui and dockers from my phone. Both work on the phone even though the laptop still can't access them. So this is some issue with the laptop, not unraid I think. This isn't the place for windows troubleshooting so I'll mark the topic as solved.
