Ollama server resolves to host.docker.internal regardless of endpoint set in .env file

[lavinir]

Describe the bug I'm trying to run letta in docker connected to an ollama service running on the same host. I'm using an .env file with the following vars: LETTA_LLM_ENDPOINT=http://192.168.xx.xx:11434 LETTA_LLM_ENDPOINT_TYPE=ollama LETTA_LLM_MODEL=llama3.2:3b-instruct-q8_0 LETTA_LLM_CONTEXT_WINDOW=8192 LETTA_EMBEDDING_ENDPOINT=http://192.168.xx.xx:11434 LETTA_EMBEDDING_ENDPOINT_TYPE=ollama LETTA_EMBEDDING_MODEL=mxbai-embed-large LETTA_EMBEDDING_DIM=512

The server loads fine. I configure an Agent and Persona via the web interface. Then when attempting to start a chat with the agent I receive the following error on the server:

urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='host.docker.internal', port=11434): Max retries exceeded with url: /api/generate (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x72f4fd942ba0>: Failed to resolve 'host.docker.internal' ([Errno -2] Name or service not known)"))

For some reason it's trying to use host.docker.internal even though the url is overridden in the .env file. I'm also run inspect on the container when running and confirmed the correct env settings have been applied.

Please describe your setup

• Installed with docker compose
• Running on Linux (Ubuntu)

If you're not using OpenAI, please provide additional information on your local LLM setup:

Local LLM details

If you are trying to run Letta with local LLMs, please provide the following information:

• [x] Model: llama3.2:3b-instruct-q8_0
• [x] Backend: Ollama
• [x] OS: Ubuntu Linux VM (CPU only)

Can you try this with the latest version (0.5.0 - you can do pip install -U letta)? You no longer need to set all the LLM/embedding model related variables, just the following:

export OLLAMA_BASE_URL="http://192.168.xx.xx:11434/"
letta server

Hi @sarahwooders ,

Thanks it seems now the server is communicating with the Ollama endpoint and I'm able to select my models. However, when attempting a chat I'm hitting a new error complaining an Unsupported Authentication Type (I have no auth for my Ollama Server and haven't seen anything in the docs that reference this)

The Error:

I'm getting the same error with the same docker configuration:

Same for me: Letta works, local models are available for selection, but chat messages yield an error message in the log. Getting the same error with Ollama models in the latest letta server UI

[Asamsodien]

experiencing the same issue Unsupport authentication type: {auth_type}

currently using container letta/letta:nightly (9a819e78d7b9)

[lavinir]

Hit a different issue with the UI after that but for what it's worth, based on a suggestion from someone on the discord server, this issue can be worked around by moving the OLLAMA_BASE_URL from the .env file directly into the docker compose file.

[sarahwooders]

The fix for the authentication type error should be in #2018 - we'll rebuild the letta/letta:nightly image once it's merged.

If you're running Ollama locally, remember to use run export OLLAMA_BASE_URL="http://host.docker.internal:11434".
