  • Ensure your router/switch is functioning correctly.
  • For Wi-Fi, ensure the Wi-Fi module is enabled and correctly configured with your network credentials.
• Suoratoisto-ongelmat (puskurointi, yhteyskatkokset):
  • Tarkista internetyhteytesi nopeus ja vakaus.
  • Vähennä videon bittinopeutta tai resoluutiota enkooderin asetuksissa, jos verkon kaistanleveys on rajoitettu.
  • Verify the streaming server (e.g., RTMP server) is online and correctly configured.
  • Ensure firewall settings on your network or computer are not blocking the streaming protocols.
• Web Käyttöliittymä ei ole käytettävissä:
  • Varmista, että tietokoneesi on samassa verkkosegmentissä kuin enkooderi.
