PHPMessage: RedisException: MOVED

[vvsaichaitanya]

I have an AWS elasticahce redis cluster with 1 shard containing 1 primary & 1 replica
I use the configuration endpoint as the redis_host.

define( 'WP_REDIS_PASSWORD', 'password' );
define( 'WP_REDIS_SCHEME', 'tls' );
define( 'WP_REDIS_CLIENT', 'phpredis' );
define( 'WP_REDIS_HOST', 'wmkt-stg-redis-0001-001.wmkt-stg-redis.du3ngv.use1.cache.amazonaws.com');
define( 'WP_REDIS_PORT', 6379);

I get PHP message: RedisException: MOVED 16313 error with this & the plugin toggles between error state & connected state.

If i try to use the endpoint given in the MOVED error above, the redis settings page throws 504
define( 'WP_REDIS_CLUSTER', ['tcp://abc-dev-redis-0001-001.abc-dev-redis.acd.use1.cache.amazonaws.com:6379']);

Any pointers on what the right config is would be helpful

You need to use the cluster configuration, not WP_REDIS_HOST.

@tillkruss could you please give me an example of the cluster configuration?

define( 'WP_REDIS_CLUSTER', ['tcp://abc-dev-redis-0001-001.wmkt-stg-redis.acd.use1.cache.amazonaws.com:6379']);

above is not working either

@tillkruss AWS only gives a cluster configuration endpoint but it would never tell us what is a primary node.

what do I add into WP_REDIS_CLUSTER array? what if the primary changes?

[tillkruss]

Disable cluster mode on AWS, or use the correct endpoint. It works tons of people are using Elasticache.

If you need 1:1 support, we offer that over at Object Cache Pro.
