Hi Ralf
thanks for your help. If I understand correctly, in order to have a valid certificate, the website https://sitename must be exposed in internet. However, for reasons related to our clients we cannot have internal information accessible via internet. For this reason EGW, Jitsi, RochetChat are hosted on our servers and are not exposed to the outside world.
Do you think it is possible to set EGW to work with a .local? domain ?
Thanks
Gabriele
