My client is actinng up and i have done everything to try to fix it.

I have reinstalled, I have used the repair tool, and I have even tried third-party servers. My client is acting up and I have been trying to correct it for the past few hours. Last night it was not acting up but then I wake up to the new season and see that I cannot connect to the game. My ping is immaculate, and the only issue appears to be is the client. can I please get any help.
