Can you reply with the URL to the media file so we can test? Does the ‘Verify’ button work?
Here’s the URL – http://kootenaichurch.org/sermons/special/special-2017-02-19.mp3
When I click on verify, it does give me a “media verified successfully” and it does auto detect the file size without error. However, it will not auto detect the duration, which is a bit strange.
I tested the URL above with our development environment and it dues detect the file size duration. It is a bit slow though. Usually detecting this stuff is fairly quick 1-6 seconds.
Which version of PowerPress are you using?
7.0.4 PowerPress. I have this installed on another site and it works just fine.
It may be that the server cannot connect to itself. I would suggest contacting the web host and let them know your website is having problems accessing URLs to itself. It may be that the DNS is routing traffic through a proxy for the website when it should not be doing so.
