HTTPSConnectionPool SSLError

[davi...@gmail.com]

Hello everybody!

I am developing a simple python application that leverages the Freesound API to download audio files based on a simple "search" request.

The script does the following:

Upon receiving the sound list Response, I loop through the list to get the infos of each file.

The function delegated to request the info is the following:

def get_track_info(track_id:str,params:dict[str,str], token:str) -> Response:
     headers: dict[str, str] = {"Authorization": f"Bearer {token}"}
     url:str = f"https://freesound.org/apiv2/sounds/{track_id}/"
     file_type_response: Response = make_get_request(url, header=headers, params=params)

     return file_type_response

track_id is the id of the track

token is the user access token

params is the list of sound file's parameters that I want to retrieve from the database.

a possible request is hence:

https://freesound.org/apiv2/sounds/316036/?fields=type%2Cchannels%2Cbitdepth%2Csamplerate%2Cdownload

The script has been working until 2 days ago, when the loop could not finish because of the following error:

HTTPSConnectionPool(host='freesound.org', port=443): Max retries exceeded with url: /apiv2/sounds/630246/?fields=type%2Cchannels%2Cbitdepth%2Csamplerate%2Cdownload (Caused by SSLError(SSLEOFError(8, '[SSL: UNEXPECTED_EOF_WHILE_READING] EOF occurred in violation of protocol (_ssl.c:1006)')))

(this request was trying to access this link: https://freesound.org/apiv2/sounds/630246/?fields=type%2Cchannels%2Cbitdepth%2Csamplerate%2Cdownload)

I have been trying with different queries, but I don't understand whether the problem comes from a new implementation of the urllib3 library, from the server or from my program. Accessing this link from Firefox does not return any error.

Am I simply making too many requests?

I look forward to hearing your opinion

Have a nice day

Hi ddgg,

I don't think the problem is with too many requests as this would trigger a 429 HTTP response. Looks like HTTPS related but our certificate is fine and similar queries form other clients seem to work fine so it should be something on your end. Also as a suggestion, you can use the "fields" parameter for the search request so then you don't need to iterate sounds one by one to "get track info".

I hope this helps,

Cheers,

frederic

Dear Frederic,

Thank you! Good to know that there could be a 429 Response. I missed that.

I was in fact having some problem connecting to freesound.org anyway (even from a Browser). From this morning on everything works great!

I’ll take a look at the fields parameter to simplify my application.

Thank you!

Best

Ddgg
