@yoyomqs Hello there! I'm here to help you with any bugs, questions, or contributions while waiting for a human maintainer.

A similar issue was previously reported and closed. The problem was related to network connectivity, specifically a timeout when trying to connect to openaipublic.blob.core.windows.net. It was suggested to check for network restrictions or proxy settings that might be blocking the connection and ensure the necessary network configurations are in place to allow access to the required URLs [1].

To resolve the ConnectionError in your private deployment, you can create and populate a local tiktoken cache directory and configure your Docker API service to use this local cache. Here are the steps:

  1. Create and populate a local tiktoken cache directory:

    mkdir tiktoken
cd tiktoken
wget https://openaipublic.blob.core.windows.net/gpt-2/encodings/main/vocab.bpe
cp vocab.bpe 6d1cbeee0f20b3d9449abfede4726ed8212e3aee
wget https://openaipublic.blob.core.windows.net/gpt-2/encodings/main/encoder.json
cp encoder.json 6c7ea1a7e38e3a7f062df639a5b80947f075ffe6

  2. Add the following configuration to your Docker API service:

    environment:
  TIKTOKEN_CACHE_DIR: /app/api/.tiktoken/
volumes:
  - ./volumes/plugin_daemon:/app/storage
  - ./tiktoken:/app/api/.tiktoken

These steps should help resolve the connection issue by using local files instead of attempting to access the external URL, allowing tiktoken to use locally cached tokenizer files and preventing the ConnectionError in offline or restricted network environments [2].
