Hi @rkuo-danswer ,

you might need to handle SSL config in the redis_pool as well.

https://github.com/danswer-ai/danswer/blob/0d749ebd469ed056430b7c71ee36ad10980adb80/backend/danswer/redis/redis_pool.py#L29

something like:

from danswer.configs.app_configs import (
    REDIS_HOST,
    REDIS_PASSWORD,
    REDIS_PORT,
    REDIS_SSL,
    REDIS_SSL_CA_CERTS,
    REDIS_SSL_CERT_REQS
)
#...
    def _init_pool(self) -> None:
        ssl_options = {}
        if REDIS_SSL:
            ssl_options = {
                'ssl': True,
                'ssl_ca_certs': REDIS_SSL_CA_CERTS,
                'ssl_cert_reqs': REDIS_SSL_CERT_REQS
            }

        # Create the connection pool with SSL support if needed
        self._pool = redis.ConnectionPool(
            host=REDIS_HOST,
            port=REDIS_PORT,
            db=0,  # You may need to define the DB number if using non-default
            password=REDIS_PASSWORD,
            max_connections=REDIS_POOL_MAX_CONNECTIONS,
            **ssl_options
        )
