I have the same problem since today. I have been working fine from my android devices untill now. I am monitoring 15 servers.
My devices are:
- Samsung Galaxy Tab P1000 (android 2.2.2)
- Motorola Defy MB525 (android 2.2.3)
The problem looks like they have changed thier SSL certificate to rapidSSL which isn't supported on most mobile devices.
I just sent a email to the support account.
Thanks Angel.
