Unable to connect to indexer issue

Sonarr version 2.0.0.5344

Win 10 Pro ver 1909

Unable to connect to indexer: The request was aborted: Could not create SSL/TLS secure channel.: The request was aborted: Could not create SSL/TLS secure channel.:

Both Sonarr and Radarr stopped working. Both throw the error above

I’m having the same issue, and have been for about a month now.

I’m running Windows 7, and running the same version of Sonarr.

For more context, rebooting Sonarr and then retesting the indexers makes this error temporarily go away, with everything working fine for a couple of days. After a few days though, the error consistently returns.

So far I’ve tried checking the ports on my router to make sure they’re open, and updating my .net framework on my computer. Neither has solved this issue.
