IB connection lost regularly

[fallendog]

Hi, I've got problems with my IB API conection that's lost sytematicaly as you can see in the log file.
I dont think it's in relation with internet provider connection, because I use a VPS with a professional
hosting. Could it be a problleme with IB API version?

I've sent the log file by email.

Thank you in advance

Here is the information about IB API version:

Hopefully someone can help you here. Using the IB API is not currently a supported way to connect.
