Your question was asked indirectly, but it was there. An indirect question looks like this:

My thingy is broke. I tried a few things. Have some logs.

Where the "and how do I fix it" part is implicit. Which certain of our users don't see as a question. Adding an explicit question to the end:

My thingy is broke. I tried a few things. Have some logs. How can I fix this?

Makes a world of difference. I've edited questions to add this seemingly obvious line (apparently it isn't) which has stopped downvote cascades.

By my read, this is how your question managed to get closed. This is easily fixed, and I will do so shortly.

As for our support of answer-your-own-question, we actually do support it here. Admittedly, not as resoundingly as the text suggests, but we do support it. You got spat on not because it was a self-answer, but because our close-voters couldn't see a question in there.
