upgrade to the latest version. 2.1.3.
webadmin is the component of call bridge. your callbridge must be running with webadmin which requires CAsigned/Selfsigned or Public SSL certificate along with CMS License.
also disable proxy on your browser and test again.

I have quite the same issue With ipad connection on webrtc. With Android phone And chrome it Work fine but not With cma. The connection don t look working Well With safari ( because it look open safari even if you use cma). This behavior is the same as when you try to connect With ie11 or edge but we know that it is not supported in This case. So cma on ipad for webrtc is not supported?
Not really, this thread is about not being able to connect to Web Admin, your problem seems related to Web Bridge, you might want to start a new thread on that.
I've faced the same problem as yours.
Check the RAM size that you provisioned to your CMS virtual machine.
If it is less than 2 Gb, your server will function properly.
Reboot the server if you haven't already. I had the same issue and a reboot fixed it. I suggested to TAC to add that as a last step. For whatever reason a reboot fixed both servers that had the same issue. Both were an earlier version of 2.x.
