Can't create Facebook Messenger Polls with default DNS blocklists

[tredondo]

With the default blocklists, I've noticed that attempting to create a poll in Facebook Messenger leads to a "Something went wrong / We're having trouble creating this poll. Please try again later." error. After stopping Rethink, I was able to create the poll.

Can you see which domains are blocked for "Facebook Messenger" in Configure -> Logs -> DNS? You can use the searchbar to filter for just "Facebook Messenger" (assuming that's what the app is called). Blocked domains appear with red-coloured left-hand side border. There's also a "filter" icon to search only the "blocked" entries.
