Hi,

after update 3cx to version 16.0.6.641 Ssl certificate renewal Failed on Microsoft Windows 2008 R2 server (i receive a warning message this OS is no longer suppported by 3cx but all function work fine to this moment), is a OS problem ?

log indicate this:
SL Certificate renewal has been failed.

Hi Massimo,

Please take a backup from your system while you still can, then reinstall a new supported OS and install 3CX again using your backup file (during 3CX Setup wizard).

We do not test older OS versions so unfortunately any incompatibilities will not be detected or fixed in this case.

If you want to keep your old OS, then I would suggest creating a VM and installing 3CX inside the VM with a supported OS at least.
