Stuck on "joining world"

Describe the problem

Issue: Unable to Join Minecraft Server

Description:

I am experiencing an issue where I am unable to join my Minecraft server after the spawn area has finished generating. The launcher gets stuck on "joining world," despite the server logs indicating that the player has successfully joined the game.

Server Logs:

[10:52:47] [User Authenticator #2/INFO]: UUID of player **** is ************-****-****-****-************
[10:52:47] [Server thread/INFO]: ***** [/***.***.***.***:45826] logged in with entity id 521 at (-452.5, 63.0, 40.5)
[10:52:47] [Server thread/INFO]: ***** joined the game

Additional Information:

• I have tried launching the server from two different machines, but the issue persists.
• The server logs indicate that the player has successfully joined the game, but the launcher remains stuck on "joining world."

Question:

How can I resolve this issue and successfully join the Minecraft server?

Everything looks fine docker-wise especially since you see the connection logs. I can't provide any support for the runtime itself.

Perhaps contact the modpack author or the mod server type used by that modpack.
