FunkyloverOne This happened to me, too. This is because solus did not enable the systemresolve service.
You have to manually enable it via systemctl (I think).
I wouldn't worry about it. From what I read, enabling it may make your operating system more vulnerable. That was the near-consensus of reading the first few hits in a search engine...for what that's worth...
Hence I removed this command from my routine system maint.
