The download works for me in 2022.2, with the same default settings on a HTTP Caller.

Debugging an error happening in an HTTPCaller can often be made clearer by temporarily changing the logging settings. Option → Translation → Log Message Filter → Debug, to see the full details on what it’s doing.

It’s a 33 Mb file, which downloaded in a few seconds for me, so I doubt it’s a timeout error. Can you try another url (like e.g. www.google.com) and see if the same happens? If you’re on a corporate network or VPN it may be that http access is only granted for browsers, not other applications.

Yeah I also tried with FME FME 2022 and had no issues - I second the suggestion by ​@ctredinnick to turn on debug logging. HTTP Requests are one of the few places in FME where debug logging is really helpful. 

Thank you guys for your valuable input. I tried it again today, (the day after the error) and enabled the FME Log Debugger. However, everything works fine today with no errors. Unfortunately I couldn’t make use of the debugger to pin point the cause, but I will keep this in mind for next time. As for ​@redgeographics , I tried the HTTPCaller with www.google.com and it worked fine. Could have been a network thing that was temporarily causing the error. Will take note of this for next time as well. Thanks again.
