[Errno 32] Broken pipe

I am streaming quotes through websockets using the following endpoint and the python websockets module

Endpoint: “wss://stream.data.alpaca.markets/v2/sip”

I receive data for a few minutes until my code crashes with the error: [Errno 32] Broken pipe

I am not very experienced or knowledgable with internet protocols/websocket so I was hoping someone could point me in the right direction. I am wondering if this could be a server side issue. Anyone else experience this?

Here’s the traceback:

Suggest running the same code on some sort of cloud server, e.g. I use www.iDriveCompute.com with a New York data center. Nothing special about this provider, any cloud provider with the right specs will be more reliable compared to a home PC with a retail internet connection.

If running this code at home, how do you connect to the internet? Wired or wireless? A wired connection always beats a WiFi connection in terms of stability.

There are other solutions too: if you do get a broken pipe (due to a transient drop in the internet connection) you can detect this, reconnect and resume the connection.
