This can a be problem with how you have configured Odoo. I had the
same issue after configuring SSL and fixed it by doing below changes;
Once
SSL is enabled using nginx, Odoo must be operational in multiprocessing
mode in order to enable Live chat feature as Live Chat request
redirected to longpolling port in nginx site configuration file.
example:
# Handle longpoll requests
location /longpolling {
proxy_pass http://odoochat;
}
when above is configured I also had to configure /etc/odoo.conf file as something like below.
[options]
; This is the password that allows database operations:
;admin_passwd = my_admin_passwd
db_host = False
db_port = False
db_user = odoo13
db_password = False
addons_path = /opt/odoo13/odoo/addons,/opt/odoo13/odoo-custom-addons
proxy_mode = True
xmlrpc_interface = 127.0.0.1
netrpc_interface = 127.0.0.1
max_cron_threads = 1
workers = 8
note "workers", it must be set depending on your hardware configuration.
when SSL is enabled try issuing below command in terminal
sudo netstat -tulpn | grep 8072
if configuration is ok, you should see something like below;
tcp 0 0 127.0.0.1:8072 0.0.0.0:* LISTEN 8223/python3
