Corona DR, not working on one slave.

[Yanosh HRDY]

Hello, I have just finished to instal corona DR on my third PC..
I try to use it...
an error mesage appears:
"Cannot bind to lookback port (TCP 19667)
This probably means that some other app is already using this port (probably another instance of DR server)- shut it down first"

and an another:
"Cannot bind to lookback port (TCP 19666)
This probably means that some other app is already using this port (probably another instance of DR server)- shut it down first"

and a last one:
"Cannot open log file in directory
C:\Users\utilisateur\AppData\CoronaRenderer\DrData\
Error: Cannot open/read/write file
C:/Users/utilisateur/AppData/CoronaRenderer/DrData/DrLog.txt

What does it mean?

I think I have to change Port....
Master is port 19666
first salve Port 19667

is it that, and if yes how?

thank you

Well I don't understand... but it's working....
in the master PC, in the render setup, my two slave are recognized and in the render viewport in DR i can find them too....and the render is working..
Do I have to modify something even though?

this definitely meant you had 2+ instances of DR server running. Closing all of them (via task manager) and starting just one will help
