Hi,
After further investigation we found 2 issue as below
First Issue
- We use fastcgi + Apache,
- The fastcgi is triggered by a Fgi wrapper script
- The path of this script was under the “/public” folder in Slim 3 and the path was defined as /FcigWapper/Fcigwarpper.php
- When we trying our Poc in Slim 4 we moved this folder above the “/public” folder,hence Apache was not able to find the script , so we had to adjust the Fcgi wapper script path in Apache configuration.
Second Issue
After resolving the first issue, we hit the timeout issue, the reason for this was we added additional functionality to our dash board , so the default time out period was not enough to load the entire page completely, so we have taken different approach to reduce this issue.
