504 Gateway Time-Out Upgrade 4.2.4 - 4.3.1

I face the error "504 Gateway Time-out " after pushing “install” Button in order to Upgrade Cs-cart multivendor from 4.2.4 to 4.3.1.

Please help, What should I do??


This issue came because the package is not able to downloaded from the cs-cart server.

If you still face this issue. you can go for Manual Upgrade.
