Which version of Hexxit is installed on your computer and which one did you install on the server?
As I say I have the latest version of the hexxit.
That doesn't answer my question.
We have multiple versions of hexxit available. One from curse and one from techniclauncher
I just joined a technic hexxit server without any problems.
Please try to reinstall your client and the server.
Well I am at home
I opened a new aternos account because I don't want to lose my world, then I reinstalled my hexxit and checked everythig. Everything is fine, versions are same, but I can't join. Yes, both my client and server are technic hexxit. Also my friends can't join too, I think the problem is not client side.
Can you help up please 
Image of version matches:
What is your Aternos username?
And can you share a screenshot of the error message?
My first aternos username is gordinfirimin
second is for trying modpacks, it is kamillostonyou
also here is my error screenshot:
My first aternos username is gordinfirimin
That server has skyfactory installed right now
second is for trying modpacks, it is kamillostonyou
I started the server and joined it without any problem, you can see that on the log page.
Please try to reinstall techniclauncher on your computer also completely delete the modpack from your pc and install it again.
I can not reproduce any problem
No . I checked that before.
I solved that ID mismatch thing.
Solution: if you are in Turkey you have to add some codes in your minecraft java settings to solve this. Alphabet differencies cause this problem. After that you have to reinstall hexxit to change configs.
code is: -Duser.language=en -Duser.country=us
If this method doesn't solve your problem, then try to change your Windows language to English(US). It must fix
Great to hear that.
Am I allowed to use your pictures in an article on our support center to help other users which may experience that problem in future?
Of course
But please don't forget to add the "changing system language" method in article. Because, first one didn't worked for me but, my friend fixed his problem with first solution
Also I will glad if you add Better Than Wolves mod in your modpacks list, atleast add it to other section please. I know it's not a forge mod, but my friends and I will be very happy if do this
