W3 / Memcache & Multi Site Domains

Hey there! Have a wp multisite on a private VPS hosted and finally got memcache / memcached installed and working on our main site, so I can select it to perform various tasks in w3 cache

the problem is, when i go to general w3 settings for other sites in the network I see the below:

The following memcached servers are not responding or not running:

Database Cache:

Object Cache:

Page Cache:

    I hope you’re well today and thank you for your question!

    First step after configuring memcached in this case should be to just reboot your machine (or virtual machine). If it doesn’t help, access shell (SSH) and try to check memcached.log and see if it reports any errors/issues.

    You can check it by doing

    tail -f /var/log/memcached.log

    over SSH (root)

    Let me know if reboot helped and/or if log shows anything, please.

    Best regards,


Thank NAME, for their help.
