ODBC error with Access

[Francesco Cavalli]

Hi,
I create a DB on my Web space and I use it as a back-end for an Access application.
I installed the ODBC 5.3, all run very well, but some times, many times during my development, I have this error:

mysqld-5.6.30-log Lost connection to MySQL server during query (#2013)

I don't know the exactly moment when this error arrive, because I use my forms, I use some queries, I open the linked tables, etc.
I leave my PC for a coffe and when I can back it run, I leave Acces open to read an email and after it not run.
I try also to check "Enable automatic reconnect".
I find on Internet that with new ODBC release the timeout setting not exists.

Thanks for te help.
