HA Slow on RPI 4?

[Roaders]

Hi All
Recently HA on the mobile app seems very slow. It seems that when I open the app I get the “could not reach Home Assistant” page most times.
The options that I get are “refresh external url”, “wait” and one other that I can’t remember. If I wait a few seconds after this screen the UI does appear.
It used to always be super fast.
I have recently moved HA from a virtual machine on a Synology box to a RPI 4 with an SSD but I don’t know if it started being slow when I did this. It might be related to an app version update.
I have also noticed sometimes that automations are slow to fire. I press the button and it takes a few seconds for the garage door to open - but there could be multiple reasons for this and it’s not just HA performance related.

The RPI 4 should be plenty capable of running HA speedily shouldn’t it?
Any pointers to see what is slowing this down?
Thanks

Possibly this?

HA app has become slow on Android

Android app has become very slow. The following things are happening: a) When I open the app, it shows a blank screen. Then it briefly flashes a message “Unable to connect to Home Assistant”. Then the message goes away and after few seconds, the dashboard is loaded. b) If I go to Settings, the app again shows blank screen for several seconds before showing the menu. c) When I select Automations and Scenes, the screen again goes blank and after few seconds, the app shows “We couldn’t find any …

Yup, sounds like my issue. Thanks

I was going to suggest immediately creating a full backup and download the file to a different device as the usual reaction is the uSD card is dying, creating data write delays and multiple retries at reading bad cells. You mention running on a SSD, so data corruption is less likely, but I’d still download a backup just in case.

Try a different USB dock? The SSD dock is connected to a BLUE USB-2 port isn’t it? Test the SSD on a desktop?

EDIT: MaxK posts an interesting issue link - might even have seen this myself last night on a client’s system - a web login from FireFox worked, whereas the Android app didn’t.
