Problems on local network

[dkmaster007]

Hallo,


I'm having problems with Roundcube (I'm on version 1.2, but problems also appears with older versions)
The problem just come out off the blue :-/

My setup is:
Windows 10 Pro (tried a clean installation)
WAMP Server (current version, but tried older versions as well)
hMailserver (current version)

If I log in from my local network, Roundcube is stuck on "Loading", I'm not able to log on at all!
(except sometime where I'm able to come into inbox. But I can't open any mail)

If I switch to "Wifi Hostpot" from my 4G mobile phone, there is no problem!




PLEASE HELP ME, IT'S DRIVING ME NUTS!!!
