VPN not offered on new version

Hi! i've been working these days using the VPN to connect to a remote computer. Today the icon its not available, and if i connect to the remote computer, the VPN icon is grayed.

I've updated the two pcs to the same version (15.43.6), disabled the ip6 protocol on both teamviewer VPN adapters, but not results...

It's there any chance to rollback to the last working version (in the 15.xxx branch) ? couldn't find any links.

Thanks in advance
