Hello,

Could you please elaborate whether users are disconnected (SSL VPN) or they are connected (SSL VPN) but cannot access internal resources?

Cannot connect to server also using internal IP . While checking the log , there was

Hi Vishnub92,

do you got any news on this topic?

To troubleshoot getting no response from the SSL VPN URL: - Go to VPN -> SSL-VPN Settings. - Check the SSL VPN port assignment. - Check the restrict access setting to ensure the host connected from is allowed.
