Redis connection failed: invalid username-password pair or user is disabled

Hi all,
I'm starting with netbox using docker-compose and I found an issue with the latest version (3.4.0) of Netbox.

I'm not able to start Netbox because of error:

`During handling of the above exception, another exception occurred:

I'm using this netbox.env file:

`CORS_ORIGIN_ALLOW_ALL=True

EMAIL_SSL_CERTFILE=
EMAIL_SSL_KEYFILE=

EMAIL_USE_SSL and EMAIL_USE_TLS are mutually exclusive, i.e. they can't both be true!

EMAIL_USE_SSL=false
EMAIL_USE_TLS=false

SUPERUSER_API_TOKEN=
SUPERUSER_EMAIL=

SUPERUSER_PASSWORD=
WEBHOOKS_ENABLED=true
ALLOWED_HOSTS=`

and I haven't any REDIS USERNAME or something similar.. How can I solve this connection issue? I mean, I have no idea about where to change the username (I saw that Redis need 'default' or ) .

Thank you all for your time and sorry for my english.. :)

Hi, you don't need a redis username.
Netbox / NetBox Worker connects to your redis / redis-cache servers via password.
This Password is defined in the environment files set in env/redis / env/redis-cache.env and env/netbox.env.

Just try to set a redis password in env/redis.env and env/netbox.env for your redis instance:

netbox-docker/env/redis.env

Line 1 in 39c7de4

REDIS_PASSWORD=H733Kdjndks81

netbox-docker/env/netbox.env

Line 29 in 39c7de4

REDIS_PASSWORD=H733Kdjndks81

And in env/redis-cache.env and env/netbox.env for your redis-cache instance:

netbox-docker/env/redis-cache.env

Line 1 in 39c7de4

REDIS_PASSWORD=t4Ph722qJ5QHeQ1qfu36

netbox-docker/env/netbox.env

Line 24 in 39c7de4

REDIS_CACHE_PASSWORD=t4Ph722qJ5QHeQ1qfu36

As you wrote above, your Redis passwords are empty in the env/netbox.env file.

Either you forgot to change the default passwords from the redis environment files or you left them empty.
But I would recommend you to use a password. This is the intention of the application.
Anything else will only lead to abnormal behavior.
