Server keeps crashing

I currently play minecrsft bedrock version 1.16.201 on Playstation 4. My Playstation name is Ambearsss and I am currently playing in a shared realm with my siblings. I have been having numerous issues with signing in to the realm on initial load of the realm. It usually takes multiple tries to get in. I've had this problem for 2 weeks. The last 2 days I have been logged in and the server has disconnected and kicked me out. Every time this happens I lose all progress. I have even saved and quit a few times and I still lose my progress. I get booted out usually within 10 minutes.
