Hello
I'm deploying Creatio Exchange Listener for my developing environment.
I'm following this academy guide:
I got this error message when I created the listener container:

I tested the service and its working:
{ "ServiceStatus": "Started", "version": "0.5.0", "connections": {} }
I made the creatio configuration side:
Now, I can send emails but when I try to sync the mailbox I got this error:

Hello Mohamed,
This is strange that your Exchange service returns this:
{
"ServiceStatus": "Started",
"version": "0.5.0",
"connections": {}
}even after the mailbox was used for emails sending. Please go to the mailbox settings and apply any changes there and see if you see something similar to this after that:
So you see the record about your mailbox there. Or try re-adding your mailbox to the app from scratch.
The error message you receive states that ExcahgneListener services couldn't establish the connection to the mail server. Please use this command:
ping mail_server_ip_address
from the ExchangeListener server so to test the connectivity. Also please check if the "The URL of the Exchange event processing service in Creatio" system setting has the value of https://mycreatio.com/0/ServiceModel/ExchangeListenerService.svc/NewEmail.
I've deployed the service on my end using the Academy instructions and everything is working properly so it should work as expected on your end and the problem can be in the connection between the email server and the ExchagneListener service.
Best regards,
Oscar
Dear Oscar Dylan,
Problem solved! It was a networking issue in Docker for Windows.
For everyone who may have this issue, you have to use host.docker.internal variable as your host IP address.
More information: https://docs.docker.com/docker-for-windows/networking/
Hi Mohamed,
I am running into the same issue for an on-prem dev image. You indicated the issue was resolved via "For everyone who may have this issue, you have to use host.docker.internal variable as your host IP address." Could you elaborate on that? I read the article on docker for windows networking but wasn't clear on how you implemented the resolution. Thanks so much :)
Update - never mind. Figured it out. Using host.docker.internal in place of localhost in all cases. This resolves everything and ExchangeListener is working for both syncing and sending. Thanks!! :)
Hi Mohamed,
Can you help me with following questions:
Did you use OS setup file or pull request for installing Redis?
How did you set up redis host address?
Where exactly we use "host.docker.internal" variable. The link you shared doesnt seem to work.
Thank you
Gokul
