When the app connects to e621 when they ddos protection on, the app may get a 503 error with a cloudflare challenge page. When you get through this challenge page in a browser, a cookie gets set called cf_clearance as a session token and you are redirected back to the page you were trying to go to. I suggest that when one of these challenge pages is encountered, a browser window gets opened up to solve the challenge and the app would save the cf_clearance cookie for future requests.
