Cant get banner to show up after setting it and join my own server ps5

Basically the title. I cannot get my banner to show up after doing the correct image requirements aswell as changing it to a different photo twice. Then i cant even join my own server but i can join others fine. Im on ps5. Sucks hate to say i wasted money :/ bought it today like an hour ago. Says server connection lost or something. Any help please?... :(
