"Error Connecting To Server" During Course Restore

I am getting this error frequently when restoring a course on Moodle version 3.8. The file is approximately 750MB and the server has been set as below:

  • post_max_size = 1500M
  • upload_max_filesize = 1500M
  • max_execution_time = 360
  • max_input_time = 360
Yet, the error keep on showing during the restore process.

Did you try higher max times, like 900?

This could also happen if the PHP memory limit of Moodle is too low, try 512 MB.

Assuming MySQL/MariaDB ...

Might look at web service error logs to see if there any logs for 'MySQL server has gone away'.

See info on: https://docs.moodle.org/38/en/MySQL

I have tried the options given but no success.

I realised that during the restore, I/O usage on the web server entered danger state causing the process to terminate
