I am no longer able to navigate to our site through Sahi, but it’s working fine when navigating to site normally (outside sahi).
We don't use external proxy for our site.

Either the remote server is down or not reachable
If the web site is not accessible even when the browser proxy configuration is removed, it means the server is down.

You need an external proxy to be configured.
If you normally require to use another proxy to connect to external websites, you need to configure Sahi to use that proxy.

You can configure the external proxy by editing
<sahi_root>/userdata/config/userdata.properties and setting these properties:


ext.http.proxy.enable=true
ext.http.proxy.host=external_proxy_server_hostname_or_ip
ext.http.proxy.port=external_proxy_server_port


If your proxy needs authorization, you should set these properties too.


ext.http.proxy.auth.enable=true
ext.http.proxy.auth.name=proxy_authorization_username
ext.http.proxy.auth.password=proxy_authorization_password


You should do the same with ext.https settings for https sites.

To bypass external proxy for some web addresses, like local addresses, set


ext.http.both.proxy.bypass_hosts=localhost|127.0.0.1|*.internaldomain.com
