Server has gone away during creating baseline

[amacara1]

Creating a new baseline is unsuccessful at the very end, with error "server has gone away". This happens on only one of the root packages, and it works just fine with others.
Exact query seems to be: "insert into t_document ('DocDate', [...]) values ([...])"
VPN connection to MySQL, this was never a problem in the past and other colleagues have the same issue only on this package.
What could it be the root cause, do you know, please?

Update: If I transfer DB locally, adding baseline works fine, so it must be a remote comm issue, I think

Problem solved, MySQL server was configured with a too-low value for max_allowed_packet
