Synology SSL not updating

Im using Docker version of HA on my Synology NAS for about 2 years.
All the time I use build-in Let’s Encrypt SSL like in this topic here

Yesterday I noticed that connection via is broken because of expired certificate.
As always I export cert files from Synology and add this files to /config folder, after that I rebooted HA.

Usually it was enough, new certificate was loaded and connection works. But yesterday that procedure doesn’t work.
Via App I have en error 1202 about certificate
Via browser I have notice of invalid SSL NET::ERR_CERT_DATE_INVALID
but in details it’s valid → Expires on: 29 dec 2021

As anyone have similar problem?

What’s more in logs I see:

2021-09-30 13:21:40 ERROR (MainThread) [homeassistant.components.yeelight.config_flow] Failed to get properties from Failed to read from the socket.

But I have no more use this integration, so it seems like HA reads old config file.

This is the problem:

OK. So we can do with that? :slight_smile:

I’ve changed for ZeroSSL, now its working.
