From today, access to the backend of my chauffeur shop is suddenly unavailable. When I try to visit any page in the backend (/ admin / users, / admin / orders, etc.), the page just loads for a long time until it expires, and I get a common error page.
When I look through the magazines, I always see:
Processing by Spree::Admin::OrdersController
Completed 500 Internal Server Error in 127259ms
** [Airbrake] Success: Net::HTTPOK
Errno::ETIMEDOUT (Connection timed out - connect(2)):
app/middleware/flash_session_cookie_middleware.rb:18:in `call'
or
Processing by Spree::Admin::OrdersController
Completed 500 Internal Server Error in 127520ms
** [Airbrake] Success: Net::HTTPOK
SocketError (getaddrinfo: Name or service not known):
app/middleware/flash_session_cookie_middleware.rb:17:in `call'
It started after the last deployment to a production that only changed images and style sheets. I cannot reproduce the error locally, despite having the same code and an exact copy of the production database. I am using Spree version 2.0.3
