While attempting database restore, connection timeouts

I’m repairing a site that went wrong over the weekend. Some update or something messed up the site and I’m trying to restore an UpDraft plus database backup which we believe was before the mess-up.

I’m getting the following error message after a few minutes of attempting to restore:

Request Timeout
This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase ‘Connection Timeout’.

I’ve tried the following things to see if I can get the timeout to stop (per the codex)

– stop the chron process

define('DISABLE_WP_CRON', true );

– increase memory limit in WordPress in the wp-config file

define( 'WP_MAX_MEMORY_LIMIT', '256M' );

– increase the execution time in .htaccess

php_value max_execution_time 60

None of these have had an effect on the database restore attempts. I’ve got note into the hosting company but they haven’t responded today.

Any other ideas of what I could do? If we can get this database to restore, we should be able to get the site repaired and back up again.
