Cannot login to Piwik

Hi All,

We suddenly cannot login to our Piwik installation. When logging in, the browser shows an error message stating that the connection to the server has been reset.

We have not made any changes to piwik recently. Our Piwik install is running on an AWS instance behind an Elastic Load Balancer, which has always worked until recently.

Any ideas as to what can be causing this?


Can you check your error log file on the server?

Also maybe try enabling Session in database (see faq)

We were actually able to figure this out. It was due to opcache in php 5.5.3 segfaulting apache with piwik. We have disabled opcache as workaround.
