Discussion and Answer

Not sure. Are you running TWiki with an accelerator such as fastcgi? The webserver might time out and not get the response soon enough.

-- Peter Thoeny - 2020-08-09

No. We are not running FastCGI, but it did get me to dig into it a bit deeper. In doing so, we discovered a corrupted (or possibly very old) version of HTTP::Response. Re-installing it made the error go away.

Thanks for reaching out and for your insight. Hope this helps others with the same issue.

I am glad it it's fixed, and you are up and running.
