Hassio observer keeps crashing on Synology DS718+

I am using a Home Assistant Supervisor on my Synology Diskstation 718+ NAS. 2025.05.0. Everything works fine, but my Hassio Observer keeps rebooting every 3 minutes. When I look in the logs of the Hassio Observer Container I only see this:

stderr	2025/05/09 10:21:49 Start webserver on http://0.0.0.0:80

In the Hassio Supervisor I see more info in the Container Log:

[32m2025-05-09 12:25:08.507 INFO (MainThread) [supervisor.docker.observer] Starting Observer ghcr.io/home-assistant/amd64-hassio-observer with version 2025.02.0 - 172.30.32.6e[0m

And that happens around every 3 minutes.

I have tried reinstalling HA Supervised already following the great tutorials of Marius Hosting How To Install Home Assistant Supervisor on Your Synology NAS – Marius Hosting but this keeps happening.

Hopefully somebody can point me in the right direction for a fix.
