Unable to Login - No JSON object could be decoded

[vikas027]

Hello,

In my test environment, I am running Vault 0.6.4 with Consul 0.7.2 backend and have created few users which are working as expected on CLI.

🍺  ~$ vault auth -method=userpass username=vikas
Password (will be hidden):
Successfully authenticated! You are now logged in.
The token below is already saved in the session. You do not
need to "vault auth" again with the token.
token: b0459465-e88a-0f49-54ee-13f908605e64
token_duration: 2764799
token_policies: [admins default]
🍺  ~$
🍺  ~$ vault write secret/project/myproject/hello value=vikas
Success! Data written to: secret/project/myproject/hello
🍺  ~$

But, I am unable to login thru the UI. This my basic compose file and the error logs.

# cat docker-compose.yml
version: '2'

services:
  vault:
    image: "nyxcharon/vault-ui:latest"
    container_name: vault-ui
    ports:
      - 80:80
    environment:
      - VAULT_ADDR=http://192.168.1.81
      - VAULT_PORT=8200
      - AUTH_METHODS=Userpass
#

These are the errors of docker container

# docker logs -f vault-ui

This is the error on Web UI

This is likely due to VAULT_SKIP_VERIFY not being set to "True". If you do want to verify the cert, make sure to set all the settings as needed for it.

@nyxcharon I am not using any cert. I did tried the variable, but still no luck.

This is the error
