The problem has been identified. The password of the default user needs to be configured; otherwise, the connection cannot be established.

This indicates that the Redis server is not configured to require a password for authentication.

Solution:

To resolve this issue, follow these steps:

  1. Locate the Redis configuration file (redis.conf).
  2. Edit the file to set the requirepass directive with your desired password.
  3. Restart the Redis server to apply the changes.
  4. Authenticate using the redis-cli with the configured password.

Detailed Steps:

  1. Open the Redis configuration file in your preferred text editor:

sh sudo nano /etc/redis/redis.conf

  1. Find and set the requirepass directive:

plaintext # requirepass foobared requirepass your_secret_password

  1. Save and close the file, then restart the Redis server:

sh sudo systemctl restart redis

  1. Authenticate with the Redis server:

sh redis-cli -h 127.0.0.1 -p 6379 127.0.0.1:6379> auth your_secret_password OK

Hope this helps anyone facing the same issue!

For me the error was that I was providing a password when no password was really needed. Redis Docker container is created without a password by default.

Hi , We incountered this issue while upgrading argocd from 6.7.18 (redis 7.0.15) to 7.7.14 (redis 7.4.1). So during rolling upgrade , one of the redis-server fails out with 

Connecting to MASTER ,  MASTER <-> REPLICA sync started , Non blocking connect for SYNC fired the event. Master replied to PING, replication can continue... Unable to AUTH to MASTER: -ERR AUTH <password> called without any password configured for the default user.

With this , upgrade fails (timesout) On manually redeploying argocd , it passes and HA argocd gets deployed with upgraded redis . My redis conf is default redis config of argocd in both case .

My question is why does restart works with above config?And why not the first upgrade ?

Just tested from nonHA argocd (single redis and these configs not present) to HA argocd (configs were created first time) , redis-replicas were successfully synced with master one even with masterauth replace-default-auth set as this .
