DrServer disconnect

Hello, I have a problem with the DrServer, it disconnects at the beginning of calculation.

I have new computers since 3 months, a master and a slave. I installed the 3DS Max 2017 and Corona 4 versions .. I did tests with the DrServer, it worked very well. Then recently I installed Vray to open old files. I also changed the internet access provider that manages my network.
I don’t know exactly when it started to stop working.

I send you the different DrServer logs.
I hope that inside there is the answer.
Thank you in advance.

If you have locked your view to render in render setup, it may be this, you have that index out of range error in your logs:

Good Luck

Hello Frood,
thank you very much for your answer, it helped me to solve the problem.
I changed the “Area to render” parameter of “View” to another parameter, then changed back to “view”, I saved and started rendering … and it works !!!
I don’t understand the logic of this bug but it works …
thank you very much again. m:)
