Error accessing Dashboard: "RuntimeError Unable to create a new session key"
Hi,
I am trying to access Dashboard via web browser using the url http://controller/horizon . The login is successful, but after that a page is displayed " Something went wrong! An unexpected error has occurred. Try refreshing the page".
I have checked the error log in /var/log/apache2/error.log and the error is this:
RuntimeError: Unable to create a new session key. It is likely that the cache is unavailable.
Please help me solve the issue.
Thanks.
