- System: Window 11
- Slicer Version: 5.8.1  
When I use the total segmentator extension, the Python console keeps showing the following warning during torch installation:  
`WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1129)'))': /whl/cu125/torch/ Could not fetch URL https://download.pytorch.org/whl/cu125/torch/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='download.pytorch.org', port=443): Max retries exceeded with url: /whl/cu125/torch/ (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1129)'))) - skipping`.  
This warning appears regardless of whether I disable the VPN.
