I am seeing the open events in Mailguns UI. So seems they are getting through and opened ok.  
Just some communication back to Ghost isn’t happening?

I see quite a few `Fetched 0 events and aggregated stats for 0 emails in 236ms`

EDIT:  
Not sure if these logs help? Seems like there is some kind of error happening:

```
