I can't log on Kitpvp and OPpvp with Optifine/other mods. Anyone know why? It literally crashes my Minecraft....

 

It's probably because of your wifi, if you give it a break this might go away.

 

Hopefully I'll try today, ty.

 

It's your computer, remove all the clients then you should be good to play it?

 

Clients as in hacked clients? If that, I don't have any it shouldn't matter.

 

Try using different versions of foptifine. Some of the versions aren't compatible with certain forge clients.

You can't even load the game without a client.

 

Well remove the mod / hack clients..

 

I've had the same problem before, and the times I was able to log into the server it would crash. Here's some tips to help that I used. I can't use optifine and only 1.12 so maybe that's the problem.
- Remove every client and try reloading 1.11 or 1.12 again and re download it.
-Try another version of optifine/ client (Not a hacked client :/)
-Troubleshoot your internet
-Try running an anti-virus program onto your computer
-Clear some things off of your computer
-Try to download/look up a computer speed program
-Delete minecraft off of your computer, launcher and all (Save single player worlds if needed)
It might just possibly be internet problems. I have family over all with their own phones connected to my internet so sometimes I can't load anything or simply watch Netflix. Try giving those a try.

 

Oml much needed ty, I will try them when I get off work ty!!!! <3

 

No problem

 

Try restarting your Minecraft. If that doesn't work restart your modem (or your Wi-Fi). If those two don't work then restart your computer.

 

Try restarting you're Minecraft if that does not work try to download the newest version of optifine and try to log on with that. If none of those work try to restart you're internet.

 

Already know that you have been logged in several time since you are in my /friends.
Closing.
