Yesterday HA started having some odd network issues and I can’t find out what happened, or even where to look to fix it. My install is on a proxmox VM, and I updated to the newest version last week without any issue. Past that I have not touched anything so the sudden outage was bizzare to me.
My symptoms are the android app does not work unless I am on wifi, esphome can not connect to devices but the devices still work, the alexa setup I had no longer works with HA but the alexa still work in the house. If I connect to my local IP instead of my weburl through NGINX I can access plugins, but they all don’t seem to have any connection to the network. Integrations that need web access all have it, bandwidth tester, weather both work, as well as things like cameras on the network. I looked through logs and they are filled with errors connecting to some items, but I don’t know where to go to root cause this.
Anyone have any ideas on where to start with this? I have snapshots so a nuke and pave is an option but I would like to avoid it if possible. Thanks for any help.
