503 error with no PhP logs

  • I seem to be getting a 503 service unavailable error when activating the Redis cache on my site, Im using the same redis database for multiple sites using different define( ‘WP_REDIS_DATABASE’, “” );

    After checking the php error logs it doesnt have any indication of the issue.

    Any ideas would be appreciated.

    Thanks
    -Daniel

    Do all sites use a unique WP_REDIS_PREFIX?

    Can you try setting a unique WP_REDIS_DATABASE for each site?

    All sites are using a unique prefix and database

    You can try running a redis-cli FLUSHALL call to make sure all the caches are flushed once. If that doesn’t help we need Nginx and PHP error logs to try and help you with the 503 warning.
