Error: An error occured while trying to send data: error (Gateway Timeout)

Overview: This article describes how to resolve the Error: An error occured while trying to send data: error (Gateway Timeout) while uploading files from desktop machine to remote server.

The Timeout parameter sets the maximum time in seconds that Apache will wait for certain events, such as receiving a request, sending a response, or waiting for a connection. The default value for this is typically 300 seconds (5 minutes); which is bydefault set in debian-based linux servers(ubuntu & debian).

In Rhel-based O.S,(Almalinux, Rocky linux etc.):

Step 1: To resolve the above error, add the Timeout parameter in the apache configuration file. Refer to the steps below.

root@gateway :~# echo "Timeout 600" | sudo tee -a /etc/httpd/conf/httpd.conf > /dev/null
root@gateway :~# grep -v '^\s*#'  /etc/httpd/conf/httpd.conf | grep -i 'Timeout'
Timeout 600

Step 2: Restart the webserver and access Ezeelogin GUI.

root@gateway :~# systemctl restart php-fpm httpd
