Laravel memcached

I am getting error like this php artisan cache:clear

Failed to clear cache. Make sure you have the appropriate permissions.

in my .env

CACHE_DRIVER=memcached

i have storage/framework/cache/data directory

in my Macbook m1 brew services info memcached
memcached (homebrew.mxcl.memcached) Running: ✔ Loaded: ✔

how can i solve the problem?

I tried to add a php extension for memcached like extension=memcached.so, but it didn't help. tried to restart memcached (brew services restart memcached), it also not helped. i do not know how to solve this problem, anyone knows the reason of error

Same happened in my case, problem was related with memcached port.

1. Check you config.cache.php file if default value is 11211

...
'port' => env('MEMCACHED_PORT', 11211),
...

2. Check your .env file you may have MEMCACHED_PORT variable with different value, remove it or set

...
MEMCACHED_PORT=11211
...

if default is not exists in config file
