I'm getting a big headache with this issue and can't find a solution. I have the following setting.
An IP Camera connected to a Fritz.Box which is accessible via a dynamic DNS from selfhost.eu. And I have a Webserver with Apache2 with a ProxyPass to this xxx.selfhost.eu-URL. When someone access my webserver he will get a live update of the webcam because the ProxyPass works fine until the Fritz.Box gets a new IP-Address. Only when I restart the Apache2-Server it will work again, so my idea is that maybe Apache just caches the IP-Address and I've to stop that but I'm not sure.
Maybe someone has an idea. Thank you!
Here my ProxyPass-Setting
ProxyPass "/tmpfs" "http://xxx.selfhost.eu:59677/tmpfs"
And here some related Log-Error from apache
