Error using memcached "RuntimeError: Unable to create a new session key. It is likely that the cache is unavailable."

Using Django
#1

I guys.

I´m using Django 3.1.6 with the sessions, but for performance i´m trying to add memcached but without luck.
In the settings added:

SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': '10.200.1.53:11211',
    }
}

installed the memcached and the packaged python-memcached.
But when i try to store anything on the session the server crashes with the following error:

RuntimeError: Unable to create a new session key. It is likely that the cache is unavailable.

Thanks!

You’ll want to verify that memcached is running and listening to that address on the specified port. Since you’re specifying a non-localhost IP address, you need to ensure that memcached isn’t just listening on a loopback address (127.0.0.1)
You’ll also want to ensure you have no firewall blocking access to that port.
