PROTOCOL_ERROR

[faassen]

Recently I tried to listen to the System Mastery podcast. The feed's here:

http://feeds.feedburner.com/SystemmasteryPodcasts?format=xml

It's hosted on Wordpress. The feed loads fine but I get a PROTOCOL_ERROR in AntennaPod. I get the same error in Pocketcasts. The audio files download just fine with desktop clients, curl, etc. The System Mastery folks are at a loss as they didn't change anything, but were getting reports from their users things didn't work properly.

I went looking around and found this issue:

square/okhttp#1897

so it's possible that there is some change in Android 5.x that in combination with a server change (HTTP 2 support on part of Wordpress?) triggers this problem.

I recently learned another podcast, Heavy Cardboard, also hosted on Wordpress, is experiencing very similar issues with Pocket Casts. According to them Pocket Casts is working on a fix but I figured I'd inform you too.

That's certainly not good. Seems like there may be an easy enough workaround though.

I believe I have the same problem with the following feed: http://feeds.feedburner.com/telardelgeek

The feed loads fine in AntennaPod (I can browse episodes, the episode list is updated when new episodes are published, etc), but if I try to download any episode, I get a "stream was reset: PROTOCOL_ERROR" (the error message may not be accurate, as I'm translating from the spanish message).

Also I noticed that I can play episodes with the "play without download" button (the error only appears when downloading an episode).

I am using AntennaPod v1.3.4.1 on Android 6 build MRA58K, on a Nexus 5.

Yeah, it all points to a problem with servers supporting SPDY and the OkHttp library we use.
Streaming is supported by Android itself, so OkHttp is not used here.

SPDY Protocol Not Enabled!
Seriously? This SSL/TLS server is using the NPN Entension to tell browsers it supports alternative protocols, but SPDY is not a protocol it supports. The server is not making SPDY an option.
