Hello Patrick levy-Rosenthal,

Thanks for reaching out.

The log files can contain sensitive information, such as IP addresses or usernames. In order to avoid unauthorized access to such sensitive information, Contributor or Owner roles are required. You may refer to the following link for more details on it - Security considerations for monitoring data.

Please let me know if you have any questions.

I am also getting this issues with trying to view the log stream for my web app. This was working a couple days ago. I have the owner role for the whole subscription this resource is in. I have also tried to add myself as the owner role of the specific app service resource.

Same here. I had to refresh the page several times and change Web app in order to get it back again.

@Praveen Kumar Gudipudi I have the "Contributor" role, and I also see the issue, so it is likely not a permission issue.

Refreshing repeatedly eventually allows me to connect to my log stream, but then if I leave and come back, the issue returns.

A similar problem was reported one year ago. A Microsoft employee acknowledged the issue and reported that the product team is working on removing the incorrect banner: https://learn.microsoft.com/en-us/answers/questions/1661185/log-stream-is-showing-me-error-this-feature-requir

Edit: A coworker with "Owner" role also cannot access the log stream and gets the same error.

Hello Patrick levy-Rosenthal,

Please check function app integrated application insights status.

Patrick levy-Rosenthal,

We are able to reproduce the issue from my end by removing app insights connection string variable from environment variables of the function app.

After configuring back i am able to connect with log stream

Please check your application insights connection string and let us know with an update.

@Praveen Kumar Gudipudi its not likely that its the removal of application insights connection string as its intermittent. Each user would not be randomly removing and adding the string back in

Same issue here. For one webapp in particular. The other ones don't have this issue
Removing and adding the connection string did not help.
Sometimes after refreshing, restarting webapp and multiple retries it is succesful in connecting until it looses connection again.

I have this issue as well and it happened very recently. I can confirm that the application insights variable is set correctly as well.

I also have this issue on multiple Web App services – sometimes it works, but 90% of the time it doesn't work. The issues started happening recently as well.

I've tried adding monitoring roles for the resources, in hopes of fixing it, but it was only intermittent.

I seem to find when I click refresh in the top icons bar then go to open log stream it works most of the time - hopefully that helps

Issue occurs with all my apps right now.
Never had this before. The CLI approach works for me. Reliable and fast.
az webapp log tail --name <app-name> --resource-group <resource-group-name>
