MiCollab Client - lost connection

[jsnapp]

MiCollab Client 6.0
Remote worker is using a Windows 10 Home, Version 1607, OS Build: 14393.1198 and getting connection lost.
I user her credentials on my Windows 7 laptop and works fine.

Besides upgrading the phone system, is here a fix for this issue?

What is the version of MiCollab server you are using?

Not sure where to find this info, but is this what you need?

MiCollab 6.0.40.0
Mitel Standard Linux 10.1.26

This was copied from the bottom of MiCollab Client Service tab.

Yes, that's the info. I had the same issue with version 6. Windows 10 has an update that forces a security protocol that version 6 does not use.

Not that I recommend this, but you could uninstall the most recent updates to windows and then it will work for a while, until the next round of updates gets installed and cumulatively fixes the uninstalls and does it again. If it's a remote user that might be next to impossible. And in general, not really advisable anyway since that's likely to create more issues than it solves.

iOS 10 had the same issue so we did end up having to upgrade. After the upgrade version 6 of the client did work so you don't have re-deploy everyone at once.

I know it's not what you wanted to hear, but if it makes you feel any better I feel your pain.

The registry snipit that would make this old version work would be

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\Diffie-Hellman]
"ClientMinKeyBitLength"=dword:00000200

If you add this to the affected pc and reboot it should connect again. This isn't best in the long run as an upgrade would be best.

Thank you John, but I added the .reg to the Windows 10 device, restarted and still connection lost.

HI, we had similar trouble after windows 10 update on Micollab Client 7.3.  Micollab server doesn't support FIPS. That's why you need to disable it in windows registry.
Go to : Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Control\Lsa\FipsAlgorithmPolicy
Change the value: Enabled to 0 (it was 1)

Hope it will help someone.
