[Fixed] Party failed to start [Network error 450]

@lmnmst  Thank you for taking your time to write the post. 

I have an iPhone Xs with iOS 13.5.1. Everything is standard (nothing is modified or hacked) and I have not installed any apps before the parties stopped working for me (but I'm not sure if there were any iOS updates in that timeframe). However during the last 'working' party 2 weeks ago my wifi went down, so I had to switch to data. However the next party (a week ago) I couldn't host. 

Just to recap with some details: 

- June 15: party hosted at 4:30pm UTC, WiFi went down during the party (maybe 5-10 minutes after the party started). I would say the party was rather slow... I remember putting some party item out of the storage for the friends to use, and it took some time for it to appear at the party for my guests. Usually the next time the guests reenters the party, the party item is updated. My friends in the chat were saying that they had to reenter my party several times, so it took some time for it to be synced. I blamed it on my data connection. 

- June 22 6pm UTC: I couldn't host anymore. 

I have three devices with three TSM accounts: 

• iPhone Xs (with my main account where I can't host now, but I hosted every week for the past two years)
• iPad (with my second account where I can still host, and I used this device to load my main account and I still couldn't host)
• iPod Touch (with my third account, where I can still host). 

All three devices are connected to the same WiFi network, so I don't think it is a provider/network/router issue on my end. But just in case I used my data-plan, and I still couldn't host. 

Since I used both iPhone Xs and iPad with my main account and both parties were not able to be hosted, I don't think it is a device issue too. 

I don't want to factory reset my device just to check if the issue is resolved. I would definitely do that if that was a device issue (but then my main account's parties would work on the iPad, but they didn't). 

I believe it is clearly the account issue. 

Can it be due to the cloud service I'm connected to? 

Currently my game is only connected with GameCenter account . It used to be connected with EA account, but I had some freezings last Fall and it was suggested that I turn it off as one of the debugging steps (see details here  - Game Freezing ). I asked EAHelp if I should reconnect EA account after I got my rollback, but they were hesitant about it and I never did. I can probably reconnect it now, but I'm not sure if it helps... I definitely don't want to bring freezings back. 

I also used to have a Facebook connection, but I had to close my facebook account late April and therefore I unlinked it too. 

@yani_tsmThank You too. I'm out of doubts that's device and network thingy.
I'm sorry that my workaround is in Android. In any chance, rather than acc links, what about acc sync.
Are the game account has sync option toggle in the phone setting? How about Game center sync?
Are there any chance the game sent doubled unsynced packages sent that makes that error.
Could you try to turn the sync off then on again and try hosting it.
There's a possible way as someone have the problem with other game.
Please try this with game app closed.

It's just a maybe

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.

@yani_tsmThanks to trying. Even though I think that might work. I'll go seek another possibility.
What if someone in the friend list are not able to invite that caused the error. But that debug message should be on server side. We shouldn't have that error message.

Chin Up!

Edit: I see solved problem, says it needs to retire one sims (This Topic)  then problem error 400 before March solved by an update.

I'll go silent as this is no possible workaround from client side. ☹️

@cheryl661166 Thanks for the report! We're looking into this 🙂

@EA_Kipling  Party no longer gives me an error after the recent update. 
The game just crashes on my end. The guests can still only bring one sim in, and if they leave, they are not able to return.
