I set up my oc9. Everything runs smoothly I have friends that access the server with their users and use it as intended.
Yet my parents have trouble accessing it:
If they can connect it takes forever. Yet, mostly Browser times out. When I use my mobile in my parents WLAN I have the same issue when I sit at the same place using 4G I everything works as it is supposed to. The bandwith of my parents network is not the problem (Youtube streams in 4K). Hence it's got something to do with the settings - most likely in the router. Yet, I have no idea what I should look for. Any ideas?
