Hi,

We recently did a upgrade from CF2016 to CF 2021 and a couple of our functionality is not working. Getting the error <servername> didn’t send any data. ERR_EMPTY_RESPONSE

The request has exceeded the allowable time limit Tag: cfoutput The specific sequence of files included or processed is: /var/www/html/WW/App/index.cfm, line: 8

How could we resolve this? Any help is appreciated very much.

Thanks

Sajan

I would first check for connection problems (network, database, web server, etc. ) and browser cache.

Then, restart ColdFusion.

We need to find what may have hung up. It's NOT the cfouput. I have a blog post on that, ("Lies, damned lies, and request timeouts").

Show us what precedes line 8 in the index.cfm file, even if there's "no cfoutput on line 8". Be sure to remove any sensitive data, of course.

And show us what's in any application.cfm or .cfc. If it's larger, consider attaching it as a file.

Or maybe someone will offer a different thought.
