if you're playing on steam try putting -nosteam in the launch options, i had this problem and it worked fine after i did this.

Properties > General > Launch Options

Same here. Problem persists since 4 weeks now. Tried to uninstall and install four times already, no solution. All updates running through anytime. What happened??

No news on support? Did the dns flush with no results. If I'm going to lose days of xp for mastery pass (which i've BOUGHT) I'm gonna sue Wizards from my country.

VPN is my last resort now

after a day the problem returns and resistive. did the dns flush but no help. I am gonna be crazy

hey I did this an it worked

it happened to me too

Same problem recurring now. It's been happening a lot this year and is worsening. I play from Singapore.

I have the same problem.

I thought it was resolved... What a pain.

at least i'm not the only one. Mexico here.

Same here. Problem started a few days ago. I live in Europe and i never had problems with it. But suddenly it started to appear but i was still able to log in if i reconnect but now it seems im locked out permanently.

.... again.

Been getting this message for months, both on android and PC, wifi and mobile data. Works intermittently, but no noticeable logic behind it.

Same problem in PC. I regret that there is still no solution :(

Every time I try to connect my account on the Android app, on my cell phone or tablet, it shows this connection errors.
It is worth mentioning that I am connected to the internet, I have tried restarting the application several times and I have already tried reinstalling the app, but the error persists.
Through Steam, on the notebook, the game works perfectly.

I can't find a fix for this after a few days. I'm having the same issue on my phone, steam and on the arena launcher outside of steam. I'm inside the US unlike a lot of the other people who seem to have this issue so I don't understand what is happening. Other games will load and connect to their servers just fine so it must be on the Arena end.

Same problem.
Tried everything, nothing helped. The only way to make it work is to use a VPN, but that isn't really a solution.

Fu wizard of the coast... i have network issues for 2 days already, do something, i switched off my whole firewall and antivirus system already but nothing... do something already

I am still having this issue (in Europe) after a reinstall of the native client, and downloading the Steam version to a different hard drive. This is unacceptable.

Having this same trouble again for 3 days now...
