Django unable to send email using uWSGI - django

Question

My django project sends email verification correctly till its using uWSGI, when i run it with uWSGI i am unable to send email, it sometimes sends as well sometimes it doesnt.
it doesnt show any error in console
Nginx config:
upstream django {
server unix://ucurs/ucurs.sock; # for a file socket
}
# configuration of the server
server {
# the port your site will be served on
listen 7000;
# the domain name it will serve for
server_name 127.0.0.1; # substitute your machine's IP address or FQDN
charset utf-8;
# max upload size
client_max_body_size 75M; # adjust to taste
location /log {
access_log off;
error_log off;
uwsgi_pass django;
include /ucurs/uwsgi_params;
}
# Django media
location /media {
alias /ucurs/media; # your Django project's media files - amend as required
}
location /static {
alias /ucurs/static; # your Django project's static files - amend as required
}
# Finally, send all non-media requests to the Django server.
location / {
uwsgi_pass django;
include /ucurs/uwsgi_params; # the uwsgi_params file you installed
}
}
Django library used for sending email : https://pypi.org/project/django-email-verification/

EDIT 2
Tcpdump from django server shows no traffic for mail, so issue is in uswgi

EDIT 3
I have finally confiremd issue is in uswgi configurations, as i tried proxy pass django development server and it works fine
proxy_pass http://ucurs_backend:8000;
# uwsgi_pass django;
# include /ucurs/uwsgi_params; # the uwsgi_params file you installed
Observation
closing uwsgi server sends all mails
