I’ve set up a TorProxy on my Ubuntu server for web crawling due to specific network requirements. When my crawler begins to operate, it functions correctly for about 3 to 4 minutes. However, after this period, I receive a 490 response code, causing the TorProxy to malfunction and disrupting the crawling process. Before encountering the 490 response code, the crawling proceeds smoothly. Could someone assist me in understanding why I am receiving this response code and how to resolve this issue?
