eCatcher : Impossible to connect to Ewons : VPN Tunnel error


I get this error when I try to connect to an Ewon from eCatcher :

VPN Tunnel error: CreateFile failed on TAP device : \. \Global{79AFD1DA-AAB-472E-BF8B-9D638688221C}.tap: Too many links (errno=31)

Do you know how it can be solved ?
In the mean time, I have no issue to connect to the dataloggers from talk2m web interface.

Thanks in advance for your feedback
