Hi! Newbie here, so please bear with me. I’ve been running Hassio on Rpi3 for about a year without problems. So far, I’ve successfully updated my system every couple of months. But now I’m not able to update the Core from core-2021.1.0. Also, I always get a timeout, when I’m trying to import Blueprints, or add automations. I tried rebooting the system for a few times, but that didn’t help.

Could someone please help me get this running again.

This is my system:
Home Assistant OS 5.10
Used Space: 29.5%

Here’s the supervisor log when I’m trying to update the Core:

Now that the core-2021.2.1 was released, I was able to upgrade to it without problems.
