"Connection error" when using gpt-4o (Docker/LibreChat 0.7.9-rc1)

[lam584]

After deploying LibreChat 0.7.9-rc1 via Docker and setting up my OpenAI API key, I encounter a "Connection error" when sending messages to the gpt-4o model. Simple inputs like "hello" trigger the error:
"Something went wrong. Here's the specific error message we encountered: An error occurred while processing the request: Connection error."

Steps to Reproduce:

1.Deploy LibreChat from source (Docker)
2.Register account and add valid OpenAI API key
3.Select gpt-4o model
4.Send any message (e.g. "hello")

Relevant Logs:

2025-07-13 08:39:34 error: [api/server/controllers/agents/client.js #titleConvo] Error getting custom endpoint config Config not found for the openAI custom endpoint.
2025-07-13 08:41:23 error: [api/server/controllers/agents/client.js #sendCompletion] Operation aborted Connection error.
2025-07-13 08:41:23 error: [api/server/controllers/agents/client.js #sendCompletion] Unhandled error type Connection error.
2025-07-13 08:41:23 warn: [api/server/controllers/agents/client.js #titleConvo] Error getting endpoint config

Troubleshooting Attempted:

Confirmed API key is valid
Restarted Docker containers without resolution

Environment:

LibreChat version: 0.7.9-rc1
Deployment: Docker
Model: gpt-4o

Any suggestions on resolving the connection issue? Is additional endpoint configuration required for gpt-4o?

I believe this issue was caused by network fluctuations, and I have now resolved it.
