**Describe the bug**
Very often as I'm browsing stats I see in red a "Configuration Error" warning in the top right of the UI. Clicking it shows a warning dialog that includes "We can't seem to reach your worker".


**To Reproduce**
1. 
2. 
3. 

**Expected behavior**
Not to show an error

**Hosted or self hosted?:**
Self hosted, 1.8.0

**Additional context**
I have a feeling it may be due to performance issues? This instance tracks ~745k events daily. Although system load is nowhere to be a concern.
