Connection lost. reconnecting... when saving automation or script

1

Have searched and found others with the Connection lost, reconnecting thing, but haven’t seen anything that looks like mine.

Everything runs swimmingly well, but when I save an automation or script, I get the Connection lost. Reconnecting toast notification and HA GUI is unresponsive for 10-15 seconds.

Can provide more details as needed, but

*Home Assistant OS

  • Core 2025.6.1
  • Supervisor 2025.05.5
  • Operating System 16.0.rc1
  • Frontend 20250531.3

Running in a proxmox vm on a mini-pc. To reiterate, this is my only real issue, has been going on for several versions, and I’m just now irritated enough to ask the community about it.

TIA -

No one else experiences this? Any tips on troubleshooting? Thanks!

Here you go Consistent lag - #8 by ShadowFist

Also, you seem to be on a release candidate (beta) version of the Operating System:

That version was released 3 days ago, so bugs are to be expected. Do you remember if the disconnection issue used to happen before that?
If no, and if my first tip doesn’t fix it for you, I suggest you raise an issue on that github link.

Thanks. The Connection lost toast only occurs during an HA restart (expected, obviously) and during the save operation of Automations and Scripts.
The background connection suspension option is already off.
This has been happening with the past several versions, both beta and released, and I keep hoping that one of the updates will solve it, but not so far.

Thanks for looking.

Anything in settings>system>logs if you check right after it happens?

Nothing that could be even remotely related. As I mentioned, I’ve been seeing this for months. Not keen on removing automations and scripts one by one until I see different behavior, but I suppose I could do that.
