Hello, I have been failed to host a party since this Wednesday. When I want to host a party, a window is displayed, "Party failed to start ,  network error 450", sometimes its say  "party failed to start hl, network error 200".
I asked my friends in the game to see if my party has been successfully opened. My account shows that the party cannot be opened, but there is a party notification in my friend's game, and the number of my parties is repeatedly displayed. They can join , but did not display the chat dialog box, unable to chat, and then unable to return to the party, will also occupy their party attendance.
Please help me solve my problem.
Picture shows :
There are three pictures from my friend’s account. I can see that the party with me (Glitch🚫party) is being held. My friend can enter to join, but the party is malfunctioning, the chat dialog box is not displayed, and no other Party guests cannot return to the party afterwards.
However, my account will show that the party cannot be held, there is no message that the party has been successfully held, only a dialog box appears, showing network error 450 or network error 200. I found that the network error 200 is the cause of the repeated display of the party, but I don’t know what the network error 450 is. I think this is a problem with the account, not my mobile device, because my mobile phone logs in to other accounts Very normal, please help me solve it, thank you.
