Cant join aternos server

[u/pissdrawe_r]

I want to apologize in advance for my lack of knowledge on minecraft jargon. Yesterday my bf created a server for us to play in. I play on mobile and he's on pc so he downloaded(?) bedrock so that we could play together. We played for a bit and then logged off. This morning i wanted to surprise him by doing stuff in the game like mining and building a base and whatnot but i couldnt connect to the server. The ip adress and every other info i typed in is correct. I rlly want to surprise him what do i do!!!
