Hello, I have a task that restarts OpenWRT every day, and when I start it, it doesn't start DDNS. I have to run it manually. What could that be?
This is often not necessary and generally not recommended. If you are experiencing an issue that is "solved" by the daily reboot, that's not normal. It would be better to figure out what is causing the problem itself and fix the root cause. If you're not having any such issues, then there is really no reason to restart in the first place.
It's hard to say... do the logs say anything?
Let's take a look at your configs:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

When rebooting, my time and Adblock are updated, it’s so convenient for me, so I personally think this is normal once a day so that the router is rebooted
full cleaning of the cache, rupture of all connections
but again, depending on what tasks
therefore, this is not a recommendation, just an alternative opinion
what does it mean does not launch DDNS, the question is not entirely clear)
If you use the DNS provider, then you can prescribe it manually in the WAN interface
you can configure DNSSEC
you can install for example luci-app-https-dns-proxy
there are a lot of different options
Openwrt very advanced program
DNS from the provider if you use, that is, the probability that it will block some DNS, it can redirect you to advertisers or other persons ))
He can collect logs for your DNS requests
Always use the DNS supplier you trust
So maybe it's a sign from above that you have some kind of glitch, that you need to reconsider the rules of the game)
DDNS is a service that can automatically update DNS records when an IP address changes.
