TLDR: When the internet connection drops out, the update gets skipped and never tried again until the next change.

1. Is this urgent: YES
2. DNS provider(s) you use: DuckDNS
3. Program version:

Running version 2.9.0 built on 2024-12-24T10:40:42.120Z (commit 78f3061)

4. What are you using to run the container: TrueNAS "Apps" (aka TrueCharts)
5. Extra information: I've experienced this repeatedly, when the internet drops out, it fails to send an update, and then doesn't try again unless the container is stopped and restarted. What's worse, once I figured this out I saw in the logs that it only WARNS that it's doing this. It should probably be error? And also retry. The container crashing would even be better cause at least then I'd know there was a problem before I found myself unable to connect.
