urltitles: Cannot fetch titles from the Chromium bug tracker
Using an URL from the new Monorail bug tracker won't fetch the title. Trying to load one issue page logs the following warning:
warn bot1 urltitles: HTTP code 0:
https://bugs.chromium.org/p/chromium/issues/detail?id=654904
Using curl from the same machine where that gets logged works. My suspicion is that the server might be checking the User-Agent string, or the bot is not sending a suitable Accept header.
The '0' response code is returned when there is a connection error. My hunch is that it's more likely to be SSL/TLS-related.
@mwild1: good tip, I'll check the ca-certificates in the machine and the related TLS stuff.
