I have an ecommerce website built on Magento (1.9.2.3). Last night I shifted it from localhost to online hosting (BigRock) - let's call this live server. The issue is that on live server Magento is not sending any mails. Instead it gives the following error:
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Temporarily Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
The store is not in maintenance mode.
I am using SMTP Pro extension and it's self-test are running fine. On localhost, the same setup is working i.e. I can receive new order, invoice, shipment etc. mails.
I have checked the access logs on online hosting, nothing stands out. Have compared them to the logs on localhost, they both show same request and response sequence.
I have enabled logging in Magento. Got the following in exceptions.log:
Following are the content of system.log:
If I disable email communication in Magento (in Configuration > System > Mail Sending Settings) everything works fine, except obviously mail functionality is disabled.
I have checked file permissions as well, they are same as on localhost.
Cron settings are as per the guidelines. Though when I access cron.php from the browser it gives error 403.
There's an error_log file in the webroot directory. It says:
[10-Feb-2018 05:03:03 UTC] PHP Notice: Undefined index: SCRIPT_NAME in /cron.php on line 40 [10-Feb-2018 05:03:03 UTC] PHP Notice: Undefined index: SCRIPT_FILENAME in /cron.php on line 41
Right now, I am not sure where or what the issue is. I have recently begun with Magento development. Can really use some help.
Adding my comments here (since I don't have comment privileges as of now):
@Piyush: It's set to 30 seconds on both localhost and Web host
max_execution_timeor other limits
