MYSQL SERVER IS GONE AWAY - Issue 500 - Timeout set to 900

[Senior Rossi]

Hello dear Vesta community.

I'm new here in this community and with vestaq and working already some months with vesta.

I have a large DB and want import. A lot of categories and entries.
Now i want import 200MB Database as zip.

(mysql/socket 900 - Filesize UL 1024M)

Before - i get error 2006 - mysql server gone away.
Now i have figured out, i have to setup in etc/mysql.conf the keep alive timeout to 900.
Ok. But now i get the issue 500.
Sometimes it works,- if i setup new vesta to debug this error, sometimes not.
What i do sometimes right, what not. (???)

What i have especially to do/setup, that i can import large DB files/socket_timeout/keep_alive_timeout?
Who can help me please.

Thanks for that.

Greetings
