I have checked almost everything from my side. I did not find the reason for this issue. Then I made a new folder and put the related file there and tried to run the simulations from there. It started working. But after almost 100 simulation runs, I am again having the same FatalTraCIError: connection closed by SUMO.
After continus trying, it starts working but just for two or three simulations. Jacob, please could you help me.
generally, in the case of "something works and then it did not",
this will not be due to a SUMO related issue. It seems very
unlikely that the program has changed out of the blue.
So, places to start looking for a resolution could be:
your code: did this change?
your environment: did something about Python change?
your system: did you install some update, or some major
program? maybe something with the firewall?
Your issue, as you yourself have also observed, seems related to
that particular system. So, in order to solve this you will have
review the system and its setup. Maybe do some rubber
duck debugging? :-) With the information you have provided
below it's impossible to determine what caused the error; you'll
have to search for this locally.
Greets,

I was using sumo version 1.7.0. I tried
the same code on another system having sumo version
1.8.0, the code is working perfectly. But in my
system, till yesterday morning it was working, but suddenly starts giving me "FatalTraCIError: Could not connect." I reinstalled the latest version of Sumo i.e. 1.10.0 but still receiving the same error message. I have reviewed the previous discussions on the subject of the same error and tried what they suggested. But no improvement.
