I have a stream based on Icecast server. It works on most of devices and browsers, but there is an issue for example on android mobile chrome - I can run stream, but it lasts 2 few seconds and it stops. User reports as well the on other browser and devices.
This is player info from mobile, where issue occures:

I have noticed that on mobile duration is provided, but I don't know why.
This is fragment icecast.xml config, which doesn't contain vulnerable data:
<http-headers>
<header name="Cache-control" value="no-cache" />
</http-headers>
<limits>
<clients>500</clients>
<sources>10</sources>
<threadpool>5</threadpool>
<queue-size>524288</queue-size>
<client-timeout>30</client-timeout>
<header-timeout>15</header-timeout>
<source-timeout>60</source-timeout>
<burst-on-connect>1</burst-on-connect>
<burst-size>65535</burst-size>
</limits>
Of course required behaviour is no interrupting
