For files stored using Amazon S3, if the link contains a space in the file name Amazon returns a 505 HTTP version not supported error. This causes the link to turn up as a 505 error in the broken links report on the link checker. However, the link does work correctly when clicked on since the browser encodes the url before making the request.
I'm not sure if this is an issue worth addressing here, but as it is now apparently working links from Amazon S3 turn up somewhat incorrectly as broken in the link checker. I say somewhat because as far as I can tell if not for the browser encoding the link would be broken.

hass commentedThis module finds invalid links. A link with a space is invalid for sure. You need to replace spaces with %20. The message is therefor correct. Browsers have a lot of auto-correction features build in, but some browsers may fail with this link, too. You schould fix the broken links.
