SOLVED: Mitel UCA v6 MiCollab Client Connection Lost on Windows 10
Version 6 of Mitel’s Unified Communications agent now called MiCollab has had troubles connecting to the MAS / MGB server on Windows 10 since the early summer of 2016. As you can see in the screenshot to the right it displays CONNECTION LOST even though it is correctly configured and is visibly showing information from the server.
The early solutions were to uninstall some Windows Patches (KB3163018 and/or KB3172985) from June and July 2016 but that is not a comfortable solution for many. The permanent work around is to set Diffie-Hellman encryption to 512bit in the registry:
Launch REGEDIT as an admin
Expand HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > SecurityProviders > SCHANNEL > KeyExchangeAlgorithms
Right click and add a new KEY named Diffie-Hellman
Right click and add a new DWORD named ClientMinKeyBitLength
Set the value to 00000200 in Hex or 512 in Decimal
I am having a similar issue and wanted to know ...My company is in the USA and I am overseas trying to acces Micollab Client. I am getting connection Lost with the occasional calls connecting. Will my overseas IP address cause this?
The location of either the Mitel MAS or the PC trying to use MiCollab should not be causing a problem. However, distance and number of connections can be a problem for any streaming application as there is an increased likelyhood of a break in the connection with increased distance.
