Sites been running for some time and suddenly I am getting 401 Unauthorized. Using a Drupal module to purge Cloudflares API when nodes are updated. Using my API key which has been working in the past. I put a ticket into Cloudflare but it seems they respond once every 24 hours so I am asking here. What would your next steps be?
Can you share your ticket number? It seems it could be related to Single page cache purge not working
