Proxy error on Export of large XLSX file

[SWeiler_9940261]

Receiving the following error when exporting a particularly large report to XLSX.The error comes consistently at 60 seconds. Is there a timeout option for Apache that can be increased? Using a reverse proxy. 

Proxy Error. The proxy server received an invalid response from an upstream server. The proxy server could not handle the request. Reason: Error reading from remote server.

Similar error in the following articles:

• "Upload fails for some CAD files caused by the Windchill PDMLink 10.0 Methodserver hanging and restarting due to a custom service/listener": https://www.ptc.com/en/support/article/CS152895
• ""Proxy Error - The remote server returned an error: (502) Bad Gateway" when importing items to Windchill Quality Solutions using PDMLink": https://www.ptc.com/en/support/article/CS290918

It seems that the error was from Proxy Pass settings.

I added connectiontimeout and timeout settings into my ProxyPass:
G:\httpproxy\conf\conf.d\30-windchill.conf

As per suggestion in the answer from:

https://serverfault.com/questions/1014537/how-to-fix-apache2-proxy-httperror-ah01102-error-reading-status-line-from-re

That allowed me to exceed the default 60 second timeout.
