Fixed

Can't play any online servers, this is the image that pops up: 

I just reinstalled Don't Starve Together as I got a new PC a few days ago and now this is popping up whenever I try and play on an online server in DST. I have almost 100 hours on this game and want to continue playing online with my friends on it however I don't know how to get rid of this error and fix my worlds not saving.

More info about my worlds not saving: Whenever I turn on any mods in that world whether it be client or character mods etc they don't work inside the world then when I exit my world it's like it never existed. I go back into the screen of "Host a game" and it just says something like "Your first time playing?" and gives me an option to play alone or together.

(No it is not mods causing this issue I have tried with and without mods, also whenever I try to check my client_log.txt file it just says "Cannot open the C:blablabla:client_log.txt please make sure it is in the drive specified so I hope that this error message is enough, if it isn't I will try and see if the log got placed somewhere else for some reason however I doubt I will be able to find it.) 

Thanks if anyone can get back to me with a fix. <3

EDIT: FIXED, I woke up this morning and everything was magically working so I'm not sure what happened.
