Two tests chrome_proxy.lo_fi.cache_lo_fi_disabled failed and chrome_proxy.lo_fi.cache_proxy_disabled are failing with the following error.
Any idea what is wrong?

These are flaking pretty regularly - ~1/10 runs. Raising the priority.

These tests are among usually failing:

chrome_proxy.client_type.client_type
chrome_proxy_staging.block_once.block_once
chrome_proxy_xt.pingback
chrome_proxy_xt.reenable_after_bypass.reenable_after_bypass
