Hello,

I am using Opencart Version 2.1.0.1 Please let me know the solution asap.

Thanks

well, better ask your Hoster, why your MySQL server has gone away,
your Server is possibly not able or willing, to handle an OC-DB, as it should.
It's usually related to the Hosting-Fee, and a known 'habit' of very cheap servers !
Good Luck
Ernie
PS: but better never again use the word asap here, nobody owe's you anything...

This is quite a common occurrence, mysql servers will temporarily 'go away' during an update or perhaps an error situation while they restart.
It should not be down for more than a few minutes at a time and should not occur frequently, perhaps once every few months.
