Updating Plugins Fail – 504 Gateway Time-out nginx

Hi,

I’ve recently migrated a website from a shared server to a dedicated server.

The plugins haven’t been updated due to the new IP address on the new server and requesting access to the new FTP.

I’ve inputted the new FTP details, but now the plugins can’t be updated and flag up this error:

​

Update failed: 504 Gateway Time-out 504 Gateway Time-out nginx <!– a padding to disable MSIE and Chrome friendly error page –> <!– a padding to disable MSIE and Chrome friendly error page –> <!– a padding to disable MSIE and Chrome friendly error page –> <!– a padding to disable MSIE and Chrome friendly error page –> <!– a padding to disable MSIE and Chrome friendly error page –> <!– a padding to disable MSIE and Chrome friendly error page –>

Can anyone assist me with this please and point me in the right direction?

Thanks for your time
