Hi, When there are more than 9 requests close together (temporally), Wowza may start returning 403 Forbidden status codes. This is on Wowza 4.3.0. How can this behavior be disabled? ---

Hello, To be able to research on why you are getting 403 errors with multiple request, it would be best if you open a support ticket at: [https://www.wowza.com/support/open-ticket](https://www.wowza.com/support/open-ticket) for Wowza’s Support Team to further investigate. Please attached bellow logs to your new case: [install-dir]/conf [install-dir]/logs [install-dir]/transcoder [install-dir]/manager/logs If you are not sure how to get this information please see the following tutorial.

Hi, We don’t apply any DOS protection in that way. I would suggest that you [open a support ticket](https://www.wowza.com/support/open-ticket) as suggested by Jason so we can investigate this in more detail. Please include the steps needed to reproduce. Paul ---

Could this be caused by a denial-of-service protection feature in Wowza? The requests may be made from the same machine/IP address multiple times, and rapidly. After a lull in requests, Wowza may respond to requests normally again and stop returning 403 status codes. ---

I have the same issue. It was regarding the amlst feature use. if you keep sending url = [http://localhost:1935/vod/amlst:sample/playlist.m3u8](http://localhost:1935/vod/amlst:sample/playlist.m3u8) for 9 times from your browser. you will get 403 error. ---

I also have this same problem. I am using jmeter to load test my nDVR live stream. Up to 10 connections right away works fine, but anything more comes back with a 403. If I slow down the frequency of the requests, I can get more concurrency. So, were there any useful takeaways from the support request that got created from this thread? Thanks! I see this error in my logs: ```auto HTTPStreamerAdapterCupertinoStreamer.onPlaylist[?DVR]: Invalid session ``` ---

Do you by any chance use developer license? If yes, it is limiting the number of concurrent client connections to 10. Production license does not have this limitation. ---

Yes, same limitations. The pages you download the dev and standard trial licenses from even say so. ---
