Question

Some users get "Oops! We weren't able to find your Azure Front Door Service configuration."

60856927 111

I have Front Door and CDN profile with configured domain cdn.ogl.app that worked well for a long time. But today I noticed that from my location it is not reachable anymore and shows azure blue page "Page not found. Oops! We weren't able to find your Azure Front Door Service configuration...".

In the same time another users able to navigate to cdn.ogl.app normally. I also tested some european VMs and found no issue navigating to cdn.ogl.app.
I changed nothing in Azure. What can be a problem?

Hello 60856927

I understand that you were unable to access your URL.

To assist you further, could you kindly provide the following details and verify the information:

Could you please provide the error message you are receiving and confirm the region(s) where the issue was occurring? Additionally, please specify how many regions were affected. Was it limited to a single region?

Please check if any geo-filtering or Web Application Firewall (WAF) rules are enabled, specifically any rules related to geo-filtering.

If possible, kindly collect the non-working tracking reference ID (X Azure reference ID) from the access logs or HAR file when encountering the issue. You can use this reference ID to check the logs in your Azure portal.

For your convenience, you can refer to the following document for instructions on collecting the logs: https://learn.microsoft.com/en-us/azure/frontdoor/refstring?source=recommendations&tabs=edge

Additionally, we recommend clearing your browser cache and trying to access the URL again.

We have tested access to your domain, cdn.ogl.app, and it is working properly on our end.

I hope this information helps! Please let us know if you need further assistance, and we’ll be happy to help.

As mentioned in my original message, the error is "Page not found. Oops! We weren't able to find your Azure Front Door Service configuration...". https://imgur.com/a/pQ8thXv

I didn't configured such a filters.

Sent you the info in our Teams conversation.

I tested Front Door CDN functionality while connected with VPN via different countries.

With VPN I found that the error "We weren't able to find your Azure Front Door Service configuration." appears in case of navigation from Israel and Italy. With other European countries the CDN is working well. Interesting fact is that Israel is connected to the internet via Italy. Something wrong with Azure CDN routing and probably not related to my front door profile configuration. Also, as I mentioned before, I changed nothing.

I will try to reconfigure my domain cdn.ogl.app to new created Front Door. Original azure cdn domain is still active if you want to continue investigation why Azure is broken https://oglapp.azureedge.net

I created new Front Door profile and reassigned cdn.ogl.app to the new profile.
Now all works well as it was before the issue with Azure happened.
It is Azure issue but not profile configuration because I changed nothing in my profile.
