Hi there,

I am so glad to see you wrote this because I have encountered the exact problem yesterday. I was trying to reconnect my connection in AnyConnect on my iPhone 12 but the message "Connection attempt has failed due to server communication errors. Please retry the connection." kept popping up no matter how many times I tried to reconnect. I also attempted to reinstalled the app and to reset network settings but none of them worked. My iPad mini 5 also failed to connect to the same server address with the exact message, but the connection works well on iPhone 7. Initially I thought that might be a problem on my end but after seeing this post I am starting to think it might be a software issue. Could someone help us out here?

Best,

ZacL

May I also ask what's your server address that you tried to connect in AnyConnect?

Hi Zacl, you can try to update your server address and reconnect.

You may want to post this under VPN forums for better visibility.

Hi Libin,

Thank you very much. Could you help me to navigate to the forums please? If possible could you also help us to reach AnyConnect professionals who could potentially solve this problem? This seems like a very recent problem and not a lot of discussions on the internet have been posted.

Best,

ZacL

You could also put in a TAC case if you need to work with someone directly regarding the issue.

Hi, they’ve changed the server address today. You can update your server address and then try to reconnect.

Hey Yvonne2, can you advise how to update the address? I am a new user and don't know how. I appreciate your help!

[Yvonne2]

Hi, if you are using iOS, please open the “Cisco AnyConnect” app, then
click “connections”, change the server address to “xybgj.net:1443”.
After all these have been done, click “save” and then enter you account and
password to reconnect.
Not sure if this can work for you, I connected successfully by changing the
server address.

Thanks! I've got another address and it works well now. It is also XXX.NET:1443
