Please provide us with the following information:

This issue is for a: (mark with an x)

- [x ] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

  1. Download the sample
  2. Install Gremlin .NET (3.3.3) through Nuget
  3. Run the sample (no code change needed)

The sample hangs (at CreateDatabaseIfNotExistsAsync() in InitializeAsync()), as it complains that none of the write regions are available for write. See log below.

Am unable to repro this. Not sure if you want to try to get others to see if they can repro or not.
