MemcachePool::get(): Server localhost (tcp 11211, udp 0) failed with: Network timeout

php windows tcp memcached

I had the same issue, with php on Windows 10 and Memcached installed on Ubuntu (running in the Windows Subsystem for Linux)

Im my case, the problem was that localhost resolves to [::1]:

>ping localhostPinging SURFACE-PRO-FRA [::1] with 32 bytes of data:

And Memcached by default listens only on 127.0.0.1.

To solve the issue, you can make Memcached listens also on the ipv6:

$ sudo vi /etc/memcached.conf

Replace

-l 127.0.0.1

with:

-l 127.0.0.1,::1

And then

sudo service memcached restart

Or alternatively, make your app connect to 127.0.0.1 instead of localhost.
