Clint crashes while joining server

I'm a Android user. I and also some players are facing this issue:-

When we join any external server not from featured or any mojang suggested servers. The server that we add and then play so while joining the game crashes • I 3 times checked IP and port but still having this and I thought it will be fix in few days but I am facing this from 1 months and more. I attached the scenario in the attachment. Please fix this because 1/3 of Minecraft Bedrock community play on external servers.
