I created a Minecraft Bedrock Edition v.1.12.1 server. I instaled my world and I started to run it. I opened Minecraft Windows 10 Edition(the same version of bedrock) and it works. I played for about 2-3 minutes, then I opened Minecraft Bedrock Edition on my smartphone. I was waiting for about 15 seconds and is says "Unable to connect to world"
I writed the same IP and PORT that is showed on the Aternos server panel.
Please I need help very fast
