[Snapshot Pro] 504 GATEWAY TIME-OUT The server didn't respond in time.


I have this issue where I cannot successfully start using Snapshot Pro on one site. Everytime time it ends with 504 GATEWAY TIME-OUT The server didn't respond in time.

Since it is hosted on hosting using cPanel, I have limited options to set crucial settings like MAX_EXECUTION_TIME, POST_MAX_SIZE, UPLOAD_MAX_FILESIZE, MEMORY_LIMIT…. I did my best using .htaccess (even found out technical limit which I cannot overpass)… I've read and studied some existing Posts on WPMUDEV regarding this subject etc.

There is now Updraft (free) in production as an offsite backup solution, but I would like to start using Managed Snapshot instead.

Facts / settings:

— WP 4.9.9

— PHP 7.2

— cPanel 76.0.20

— Updraft free in production (working almost as expected) – exception for "Snapshot" folder

— Snapshot Pro to be used – exception for "Updraft" folder

— PHP options

max_execution_time 120

(this is max possible in cPanel PHP options, so it is overridden by .htaccess using value of 600 (at the moment) or even more; I've tried 800, 1000 and 1200)

memory_limit 512M

(this is max possible in cPanel PHP options and cannot be overridden by .htaccess…. if I tried, setting was ignored and dropped back to the default value of 128M)

— .htaccess

php_value max_execution_time 600

php_value post_max_size 100M

php_value upload_max_filesize 100M

— wpconfig.php




— Website size at the moment 3.2 GB (everything included)

— More than enough storage space left on server for local copy (temp), which is 6.1 GB used out of 20 GB

Please advise / help / … Thank you!
