Players are on the same server, but do not see each other

I’m setting up multiplayer, and I’m having a problem. Players are on the same server, but do not see each other, I have tried all the settings related to replication and visibility of the character, but nothing changes. It is also worth noting that I have already solved it once, but I do not know exactly how it happened … After that, I changed the skeletal mash and the problem returned

I was able to solve my problem here! Thank you.
