caves still don't work

could you please try again and then attach your \Documents\Klei\DoNotStarveTogether\client_log.txt ?
Also, does the client give you any error messages?

no error messages 

I can only play cave servers in offline mode

client_log.txt

We have identified a potential source of the issue and are working to fix it.

Can you double check that any firewalls you have are not blocking dontstarve_steam.exe and dontstarve_dedicated_server_nullrenderer.exe?If no error messages are happening, then what screen is the game on, and if there is text on the screen then what does it say?

If you have no already, could you start a worldgen for an online caves-enabled server and then let the game sit for about 2 minutes without pressing any keys, even if windows says the application is not responding?

On another note, please make sure all your mods are up to date (look in the mods screen off the main menu). Mod ID 373991022 (Marks CoopMap) has been removed from the workshop but you are still subscribed to it.

no firewalls are not blocking don't starve 

it always says launching server or generating world and I use no mods

I can enter a cave server but I can't launch one

I wait about 10 minutes it still not open
