|Applies to VoipNow 3.x.x!|
Sometimes, when accessing the VoipNow interface and the Call Reports area in particular, an error stating "504 Gateway timeout" might occur. This means that the web server (Nginx) could not get a response from the backend (PHP script).
This might occur because of the following reasons:
There is no perfect solution for this because it requires extensive debugging. However, you can use the workaround described below:
Make a backup of /usr/local/httpsa/etc/httpsa-admin.conf using the following command:
cp /usr/local/httpsa/etc/httpsa-admin.conf /usr/local/httpsa/etc/httpsa-admin.conf.bk
Edit /usr/local/httpsa/etc/httpsa-admin.conf and add the following lines in the http section. This will increase specific read/send timeouts to 120 seconds.
Restart the httpsa service using the following command:
service httpsa restart
If the issue persists, it is recommended to contact support.
