Hi,
you are reporting two different error messages:
First FatalTraCIError: Could not connect.
and now FatalTraCIError: connection closed by SUMO
This last error is often caused by problems with sumo (sumo crashes)
See

Best regards, Harald

Hello once again.
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.

Hello,
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 <https://en.wikipedia.org/wiki/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,
Menno

Hello once again
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 startsgiving 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.
