I can join my friends game on bedrock but they can't join me.

my friend cant join me. it keeps saying "locating server." I have gone to all the pages on this website for workarounds and nothing works. i have gone from windows to xbox and he still cant join, i have made new accounts and so has he and he still cant join. please dont deny my problem because none of the other pages are helping me. i have looked all ovr the internet and there is nothing that will fix this problem for us. i can join him and he cant join me no matter the accounts or platforms. please try to help me and not brush me off your shoulders.
