QUITTING. 2024-03-12 09:22:16 (6252): Guest Log: [ERROR] Could not connect to vccs.cern.ch on port 443 So one would see a network .problem. However, a ping to "vccs.cern.ch" works well. Atlas and Theory are being processed without any problem. Any idea what's going on? ID: 49750 · Reply Quote

This is from Ivan in an other message: In this case, the two meanings of the word "proxy" are quite different. The proxy credential is an authorisation to connect to the service; the (squid) proxy server is a caching server that saves requested files so that they don't need to be transported again if re-requested.
