i replied with a suggestion here
Hi Jgravois,
This is in continuation of the raised issue, after setting proper proxy too , same error is appearing .
Please help on this.
Hi,
I'm having "timeout exceed" when I print A0 format. I'm using the javascript api 3.17.
Apache and ProxyPassRevrse to the 10.3.1 gis server. I'm printing with a Geoprocessing service.
I already changed Apache's Timeout and ProxyTimeout but the "Timeout exceed" still happen at 60 sec.
I changed the 3 timeout services' variables as well.
I'm guessing that the timeout is happening in the GIS server and that is the answer I getting from my webserver.
I don't know what other "Timeout" variable to change.
Can somebody help with this please.
Thanks in advance
I am having exactly same issue as Ganesh. i.e. print operation works fine using ArcGIS print service but when I replace that with out ArcGIS Server print service it times out. I have done some debugging seems like when I remove all the data layers from the map object and just have basemap then my print service works but if I have those data layers added on the map then it fails (this issue doesn't happen when I use ArcGIS print service). Any thoughts?
If you all are using ArcGIS Server on Windows then you may need to increase the executionTimeout in your IIS web.config.

I found a solution changing the esriConfig.defaults.io.timeout which is 60 sec by default and incrementing timeout in my webserver as well. I'm using Apache 2.4
Tried both of the above but still same issue. Seems to be the outside ESRI print service can add the data layers and create output map but our own print service caanot access the data layers and throws timeout error.
