Event ID 41025 – Conferencing Edge Server – shows up every minute / Två event ID dyker upp varje minut

Event ID 41025 – Conferencing Edge Server

Event ID 41026 saying “No connectivity with any of Web Conferencing Edge Servers. External Lync clients cannot use Web Conferencing modality.”
This was going on forever. The next second after the error it told me that the connection was up and working fine again.

The only evidence of wrong doing was the Event Log on the Front End Server. The log was looping through Event ID 41025 and 41026 every minute !

The problem

Event ID 41024 – Lost connection to all Web Conferencing Edge Services
Event ID 41024 – Lost connection to the Web Conferencing Edge Server
Event ID 41025 – Connection to the Web Conferencing Edge Server has been restored

The solution was simple

Disable IPv6, in the registry, not in the control panel
