Can confirm this. I tried with bing. Same result. That was why it wasn't working, because of bing. Thanks! I'll probably to switch to something else now.
In the meantime I recommend Searx, it's an open-source metasearch engine.
Just to be clear Duckduckgo isn't at fault & always uses a VPN it's the least you can do to protect yourself online (If there are financial struggles ProtonVPN is a free & open source reliable alternative.).
This appears to be a duckduckgo bug. Peertube shows up in ddg for me, but I've had a few simple searches that randomly gives no results in ddg. I usually switch to ecosia when ddg gives no results.
Searching "PeerTube" doesn't return any results. peertube (all lower case) doesn't return anything either. What's funny is that "pertube" returns the correct results for "PeerTube". It seems like it works like this: If the IP requesting the search is from my country and it's searching PeerTube or peertube it's going to block the search. But why should it?! PeerTube isn't blocked here. YouTube is though.
It is weird that your snapshots don't have the safe search options shown like mine and everyone elses.
Do you have any content filters or anything like that on your devices or internet?
They could be forcing it to be strict even if you choose otherwise.
You’re in Safe search: strict mode. It probably thinks it’s a term for porn and therefore blocks it completely. Set it to moderate or off and you’ll get results.
Why should I use SearxNG?
SearxNG has rolling releases, dependencies updated more frequently, and engines are fixed faster. It is easy to set up your own public instance, and monitor its performance and metrics. It is simple to maintain as an instance administrator.
As a user, it provides a prettier user interface and nicer experience.
