CEDM doesn´t recover license switching from Zscaler to local network

I am using Creo Elements/Direct Modeling Release 20.4 and Datecode20.4.3.0 CEDM session does not recover license if started in Zscaler and switch network to an enterprise on site wifi. It is Zscaler related, because in the past we had other VPN and it was allowed to start in VPN and switch to company wifi. In both cases there is connectiviy to the license server, just doesn´t recover the session. The session must be closed and reopen. Here are the errors that I faced Typical error when a license is granted and then temporarily lost connectivity to license server: "the license server connection to these hosts is broken xxxxxx" + "the following licenses have been withdrawn and are currently unavailable".
