That error code 11 comes after a disconnection. Happens elsewhere too, in my experience.

Coming back to your infrastructure...I have been seeing this error seen in the attachment lately. This had happened last week as well. And this is not my network issue. I am using a cloud VPS service provider and the problem has occurred multiple times last week. I also trade simultaneously in other broker NEST as well and never faced this.
