Sluggish performance

Having lots of intermittent issues with hassio that seem to be down to authentication issues, sometimes asks for login details, very slow at logging in and ingress very slow.
I was running duckdns and installed Nginx, the problems seem to happen after deleting Nginx.
I have played around with auth_provider in configuration.yaml but have since deleted that. Is there any suggestions what I can do to reset things or find where the problem lies. Im running on a Nuc in Proxmox and all seems to be ok with that.

I don’t use but on my installation, in the config directory, I delete the .storage . folder. I usually copy the whole folder and then delete it. This will make HA start like fresh with authentication. (and holds other stuff like lovelace config)

Thanks I’ll create a snapshot and give that a try. Thanks.
