Lync Server 2010 - Mobile Access "Unkown Error"
![](https://techprofile.blob.core.windows.net/images/kxiRxDhY90yiViJqwChRwQ.png?8DA8A7)
Hello Forum,
In the Last Few days i wanted to Experiment around with some old systems to see how they worked.
(I wanted to work a Month in an Old Style doing nothing Important)
I am Having Trouble Setting up a Lync 2010 Server Mobile Connection. On my Android 11 Device
i installed an App to Open the Lync 2010 Mobile Settings, that is not the Issue. However when i am Connecting i receive:
"Unknown Error/Problem. Try Again Later." (I am German, it is a Rough Translation).
So i went and Checked with 2008 R2 and checked all Patches and Services were installed and Running, which they were.
The Phone is also in the Right Network Space.
I checked the Lync Mobile Log and it says it is actually trying to Connect to the Temporary Local IP. (192.168.0.253:443 / 192.168.0.253:4443)
It is receiving a Problem which is a 403 IIS Error.
On my 2003 and 2012 R2 machine it is reporting the Same.
PS: I know these Systems are all EOS / Almost EOS. It is just for Fun but i really would like to see it....
Thank you for Suggestions,
Maximilian Schäfer, greetings from GER M8s
