ffmpeg -y -i "URL" results in input/output error

[CrackerJackCheese]

Hello. As of about a month ago, when I put the command ffmpeg -y -i "URL" in a-Shell, I have received an input/output error. It used to work before then. This also occurs in a-Shell mini. Can you fix this ASAP? Thank you.

Below is a snippet of the error log:
[tcp @ 0x30301ff80] Failed to resolve hostname [HOSTNAME]: nodename nor servname provided, or not known
[in#0 @ 0x302207700] Error opening input: Input/output error
Error opening input file [URL].
Error opening input files: Input/output error

Could you give me an example of an URL where that used to work, so I can run tests? A full copy of the error log, with "HOSTNAME" and "URL" explicit would also help me in narrowing this issue.

Also, is the problem still present with the TestFlight version?
