What happened?

After adding Podcast RSS feed, the Podcasts will load/download correctly on the first run. Any subsequent updates result in Failed to get/parse RSS file.

@John9026231
It seems like the hostname for www.google.com cannot be resolved due to an error. Is it possible to access www.google.com from the machine where Airsonic Advanced is running?
Also, if you could share the RSS URL, I can test it on my end, which might help in resolving the issue.

[John9026231]

Thanks for following up. I can, its on the machine I am currently on, no issues.

Please find the below.

To also note, this is also applicable to a Patreon podcast I run into. Sharing the error message with redacted information because its subscription based.

After restarting the container, issues subside it appears.

Is there a function to ping an address within the container? Ping isnt a function from the command line.
