Hi,

I got the following error message when trying to connect to an eventhub,

Error occurred while connecting to eventhub: CBS Token authentication failed. Status code: None Error: client-error CBS Token authentication failed. Status code: None"

Can someone help here?

We have a HF in our network zone and want to connect to the MS eventhub via proxy. Which we configued within the app itself.

We use the Add-on for MS Cloud Services version 5.2.2

 

Thanks

Hi @Brenny,

I encountered the same problem today and found the issue.
In my case, the eventhub name wasn't the good one. 

It should be the one located in the properties' name field under the Event Hub Instance, but I was using the one from the Event Hub namespace properties.

Hope that helps!

HI @HappySplunker .
Yes, we found some failures within the Eventhub Names and also within the consumer groups.

But now it is working.

Thanks
