Hello Christian,

It's "Stream read error".

When does it happen - maybe after some time of inactivity?

The list of errors you can get using "SHOW VERRORS" query - either for Valentina local connection or Valentina Server connection:

HI Sergey

Thank you for the info.
It is not yet clear what makes this error happen.
Actually there is not much inactivity (~1min).

Could you run vServer with VerboseLevel =3 and send me that log after this error happen?

Found out the reason on my testsystem (Mac mini).
The Machine was sleeping, so the behavior in the app was kind of strange.

On the prod system I wrote some code to check, a reconnect is needed or not.
Works great now.

Thank you for support.
