Hi guys,
we have a ApEx instance served by two OHS and a loadbalancer in front of them.
Apex version is 4.2.6.
Everything is fine, except from the download CSV functionality in Firefox and IE. Chrome and Edge work fine.
In Firefox and IE at the end of processing instead of the file we get 502 Bad Gateway. It doesn't matter how long it takes, from one second to many, it always ends in Bad Gateway.
Does anyone have any idea why this might be happening?
Our administrator has checked the OHS and loadbalancer settings but could find anything wrong...
Thank you!
