When adding an indexer to Prowlarr, the indexer does not propagate immediately. If an immediate propagation is desired, a synchronization can be triggered by following the menu options: System→Tasks
and then clicking the refresh icon next to the Application Indexer Sync
option.
Setting up a proxy with Prowlarr is counter-intuitive and here are the steps necessary to set one up:
Settings→Indexers
and add either a HTTP, Socks4 or Socks5 proxy,Settings→Indexers
.Assuming that Prowlarr is set up to use Tor as a proxy, some indexer definitions can be converted to use the indexer onion address instead of the clearnet address in order to avoid random blocks due to Cloudflare prompting for CAPTCHAs.
