  1. Hi,
    I download your show (all the way to Oz) on Windows 10 using gPodder, but recently (the last two shows) I have been getting an error with the RSS ( feed I’ve been using.
    I get a list of all the shows available, but when I select one to download I get the same error.
    Failed: Request Error: HTTPSConnectionPool(host=’’, port=443): Max retries exceeded with url:/wp-content/uploads/2021/11/Security-278-PhoneRegistration.mp3 (Caused by ResponseError(‘too many 503 error responses’)) – inThirty
    Any suggestions?
