SSL VPN Proxy Error

Hi all,

I created a SSL VPN with full access.

I am able to connect to the VPN portal via web browser.

When trying to access an internal https service, I receive this message:"

SSL VPN Proxy Error

The proxy server could not handle the request GET/proxy/597d4bc4/https/x.x.x.x/.

Reason: DNS resolve failed.

The x.x.x.x IP is the address of the internal service and is added to the SSL VPN policy as the destination address.

When i specify the secondary DNS it will work for some time after it resolve the DNS.

After some time again i get this error message.

Could you please help troubleshooting this issue?

Thanks in advance.

Hi,

The dns server configured on firewall should be able to resolve the internal service fqdn at all times, if there is an internal dns server, you may keep them as primary dns server. Or create a A record for the internal service domain. 

best regards,

Jin

Hi,

I tried by keeping the internal dns server as primary dns server but it didn't workout. A record is already created on the internal service domain but it is not working.

Is there any other solution?
