I'm not sure if this is a squid settings problem or not, but here goes:
Setup: Koozali Server at remote site in server only mode, IP address 192.168.15.100. It sits behind a Draytek router that is configured to allow VPN access from me alone. I connect to it from my PC using Draytek's own VPN client. My PC sits behind a Koozali server in server/gateway mode (Local IP address 192.168.20.250), connected to the Internet using a Draytek Vigor 130 modem.
When I connect to the VPN I can access the remote server server-manager using Firefox by typing in 192.168.15.100/server-manager
. I can access the remote server using Putty from my PC by typing in the 192.168.15.100. But I cannot access the server-manager using either Opera or Edge. Both come back with the error in the attached screenshot.
The reason I suspect a squid setting is that I came across something similar when squid had failed to start, and only Firefox could access websites. Any suggestions/help much appreciated thanks.
