Teamcity web-interface does not work I have Teamcity on Windows machine.
When installed it, I selected the 8080 port.
I have another application on the 80 and 443 ports.
It worked fine, but now I see an error:



But if I open localhost:8080 on a virtual machine - all works well.


What happened? Maybe you know :(
How I can change port or change working to "without SSL"?
How I can move all my projects to another Teamcity?


Thanks!
Thaks for all answers. 
Teamcity began to work correctly when I installed all windows updates to my Windows Server 2012 R2. 
Maybe it depended with last Microsoft security update.
