Problem

All modules in the Terraform Private Registry show as "Setup Failed"

Cause

This error appears repeatedly in the output ofdocker logs ptfe_atlas

[DEBUG] Failed to open TCP connection to ptfe_registry_api:3121 (getaddrinfo: Name does not resolve) excluded from capture: DSN not set

This is caused by corruption of the Registry Session keys that connect TFE to the Registry containers.

For Terraform Enterprisev202205-1 or later:

This error appears repeatedly in the output ofdocker logs tfe-atlas

[DEBUG] Failed to open TCP connection to tfe_registry_api:3121 (getaddrinfo: Name does not resolve) excluded from capture: DSN not set

Solutions:

Verify the values of the session keys. SSH to the TFE server and run the following command:
- ```
replicatedctl app-config export --hidden
```
- Look for the values of these two keys.
```
registry_session_secret_key
registry_session_encryption_key 
```

- These should be 32 character strings with only valid hexadecimal values. If they are not, the keys are corrupted.

To fix the corrupted keys, overwrite them and restart Terraform Enterprise with the following commands:

replicatedctl app-config set registry_session_secret_key
replicatedctl app-config set registry_session_encryption_key 
replicatedctl app stop
replicatedctl app start
