rspec: E2E tests Can make request to service failed

Note: #735 was also for this test, but it was closed more than 10 days ago. So, I didn't mark it flaky.

Looks like this issue is flaky. :worried:

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (584c6775d10f518e5caa8d397ce845f8b4dcfcc6), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).
