Errors keep showing up in Mailgun's logs: all callbacks to ~/mailgun/notify end up being undelivered.

Might I be missing a configuration step in Odoo?

@vodwood first you need to check if you setup correctly the following:

the route from mailgun side
outgoing mail server
mailgun.apikey in Settings > System Parameters

@ilmir-k Thanks Ilmir! All of the mentioned seems to be correct. There is no problem with deliverability to and from Odoo. The problem is that the callbacks from Mailgun are not reaching the URL you have defined in your controller.

This is the error in Mailgun. As you can see, the callbacks keep retrying and softly failing until they fail permanently after several attempts. { "severity": "temporary", "tags": [], "storage": { "url": "https://se.api.mailgun.net/v3/domains/vostok.bike/messages/eyJwIjpmYWxzZSwiayI6ImNhMWE5NTUyLTMxNjQtNDdmZS04ZDQ5LTZhODc5ZGRhODdiYiIsInMiOiI1OTUxZWYwNDIzIiwiYyI6InRhbmtiIn0=", "key": "eyJwIjpmYWxzZSwiayI6ImNhMWE5NTUyLTMxNjQtNDdmZS04ZDQ5LTZhODc5ZGRhODdiYiIsInMiOiI1OTUxZWYwNDIzIiwiYyI6InRhbmtiIn0=" }, "delivery-status": { "attempt-no": 7, "description": "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 3.2 Final//EN\">\n<title>500 Internal Server Error</title>\n<h1>Internal Server Error</h1>\n<p>The server encountered an internal error and was unable to complete your request.

Hi! I have the same problem in Odoo 11, sending works ok, but callback to /mailgun/notify fails with:

500 Internal Server Error

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Server response: 500 500 Internal Server Error

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

This is my first time trying to use mailgun addon. May be something changed from mailgun side.
