AT&T Fiber cannot access Wechat (specifically Wechat servers in Singapore)

We are here to help point you in the right direction, zsliu.

As mentioned in that other article, we suggest that you contact the WeChat support group for more help with this. They will be able to help you and answer all of your questions.

Also, it looks like this is getting worked on by our engineers. They are working on this as fast as possible.

If you have any other questions or concerns, feel free to reach back out.

Thank you for choosing AT&T.

We are experiencing similar issues, not accessing WeChat, but accessing a partner site. We notice it starting around 7:30 PM and lasting past 10. I hope AT&T engineers are working on this, it has been happening for roughly a week now. We are seeing the path ending at the same router in AT&Ts network.

We're here to help with your third party app, @edmls!

Just as Marc mentioned in his previous post, we are recommending that customers contact WeChat support to get further assistance at the moment. 

We are aware of this ongoing trend and we do have the appropriate team working on this to resolve this as soon as possible.

Let us know if you have any other questions! Thank you for choosing the AT&T Community Forums!

FYI, it is happening again tonight. The site I am experiencing difficulties with is not WeChat, but another site that I have been working closely with the vendor on for this issue. Unfortunately as this path stops in AT&Ts network, there is nothing they nor we can do about it.

Also, as mentioned, it works with other ISPs and it works before about 7:30 PM every day. Right now I can get on my Verizon phone and access the URL, however if I switch my phone to Wifi and use AT&T, I cannot access the site. Here is the traceroute again.

Please send this to your network team as AT&T is the only one who can fix this.
