Thank you

Sometimes the online book can be quirky. And it will go "out of book" when it clearly isn't. Not sure why. You aren't the only one who has experienced this.
Since this is online book, maybe sometimes there are connection/server problems with it. I would advice to switch to local books when it happens and cross fingers they improve servers soon.
