(Bedrock) Cannot connect to friend's survival multiplayer

Hello. I am a server moderator for a smp which we play in private, I cant seem to connect to the server, both fails were both around 11PM including this connection fail. I got in successfully during 9AM (Eastern USA Time)

The Error:

Unable to connect to world.

P.S. When i try to join the server is online.

Oh i forgot to say that it worked, Thanks!
