The traffic manager domain can be removed only through the Traffic Manager.

Osena, Darren 0

Im using Ansible (ARM template) to provision resources need for my app function.

The flow of provisioning:

Traffic manager no endpoints
ASP, Function
Bind cert
Traffic Manager with endpoints

This work, but for some other functions (we have 10 to provision), it fails. The error is:

The traffic manager domain (*.trafficmanager.net) can be removed only through the Traffic Manager (happens on step 3)**. I noticed that, supposedly step 1 should have removed the binding but it doesn't. Now when checking the resources in the portal, there's a TM without endpoints but the app function still has the traffic manager in the custom domain. Deleting the TM custom domain in the app function manually would also result to the same error, but when I try to delete the endpoint in the TM I'm unable to do so since it's provisioned without endpoints.

** What I'm doing is I have to add the endpoint manually then right after I will have to delete.

Hello @Osena, Darren ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I'm not sure I understand your issue. Could you please confirm if you are trying to add and remove endpoints from an existing Traffic Manager?

And the error you mentioned is received when adding new endpoints because the previously added endpoint still has a mapping to the Traffic Manager even when it is no longer available in the traffic manager endpoints?

Regards,

Gita

Hi @GitaraniSharma-MSFT , thanks for checking this.

The issue I'm trying to convey is that I'm having problems to redeploy an azure function with traffic manager. The root cause of the error is *when adding new endpoints because the previously added endpoint still has a mapping to the Traffic Manager even when it is no longer available in the traffic manager endpoints.
*
For example, I have this app function with the traffic manager domain still in bind.

Supposedly this should have been removed, as I redeploy an empty traffic manager (without endpoints).

I have the same steps and arm templates for provisioning my other azure function but there are instances that it won't work as expected resulting to this traffic manager issue.

@Osena, Darren , just want to confirm a small detail.

You mentioned "Deleting the TM custom domain in the app function manually would also result to the same error"

Did you try deleting the custom domain manually from the app and it gave the same error?

@GitaraniSharma-MSFT yes I tried deleting the custom domain manually from the app itself and gave the same error.

@Osena, Darren , I checked internally but couldn't find any known issues that could be resulting in the above error.

When I tried to delete an existing endpoint (function app) from Traffic manager, it automatically removed the custom domain from the app. I tried it a couple of times and it worked without any issues.

I've reached out to the Azure Traffic Manager Product Group team to check if there are any ongoing issues which could cause the issue you are facing. If I find something out, will share an update here. If there are no ongoing bugs, then we may need to create a support request for further investigation on this issue.

Gita

thanks @GitaraniSharma-MSFT , also just for clarification. Deleting the traffic manager resource itself will automatically remove the custom domain from the app right?

@Osena, Darren , yes, that is correct. Since the Traffic Manager profile will no longer exists, the custom domain will get auto removed.

@Osena, Darren , apologies for the delay in response.

I checked internally and also discussed this with Azure Traffic Manager Product Group team but couldn't find any similar ongoing issues.

The Azure Traffic Manager Product Group team suggested to create a support request and engage the backend team for further investigation.

So, I request you file a support ticket for this issue.
