Yacy wasn't working, I wasn't able to load anything (the homepage and so on). I had to redirect the "https" port (TCP) in my Internet box to my UnRAID machine. I'm using Unraid 6.9.0-beta25. YacY is up to date. Here is the error message I had: it was unable to connect to other peers. So if you also have this problem, you now know what to try.
