[mayur200]

My saas module was working perfectly fine on before one week but I don't kniw if someone has made any changes in nginx. I am facing this issue when I try to sync server
_```
raise Warning('Reason: %s \n Message: %s' % (res.reason, res.content))
Warning: Reason: NOT FOUND
Message: b'\n<title>404 Not Found</title>\n

Not Found

I have almost tried everything:
1) I have restarted nginx server 
2)My DB filter is = dbfilter = ^%h$
3)My main db config file:
_[options]
; This is the password that allows database operations:
admin_passwd = admin
db_host = False
db_port = False
db_user = odoo12
db_password = odoo
xmlrpc_port = 8016
logfile = /var/log/odoo/odoo12e_robin_saas.log
addons_path=/opt/odoo-12.0.post20181119/odoo/addons,/opt/odoo12enterprise/enterprise,/opt/odoo-12.0.post20181119/odoo/robin/RobinEnterpriseSaas
