Network error. Can not connect to VPN server in Mac OS

Hello,

 

 

I have a problem with Forticlient VPN connection. When i try connect to server i got massage "Network error. Can not connect to VPN server". I'm using domain name in Remote Gateway. If I use the IP address everything is ok.

 

Mac OS 13.3.1 (but it already happened to me in previous versions)

FortiClient VPN for Mac 7.0.7.0245 (but it already happened to me in previous versions)

FortiGate 60F 7.0.11 (but it already happened to me in previous versions)

 

Ping by domain name works ok, access by web browser by domain name works ok.

 

A Windows computer on the same network as the Mac connects perfectly by domain name.

 

 

Anyone know how to fix it?

 

Thank you,

Hi LD,

 

We are seeing "SSL_accept failed" error. Could you confirm if you are getting the certificate warning when using FQDN?

From MACOS 10.15 and above, there are new security requirements for Apple devices:

The solution is to buy an ssl certificate since otherwise Apple devices updated to the latest versions of operating systems do not connect. We added a certificate to our Fortigate and now everything works fine. Thank you

Dear LD,

 

Thank you for posting to the Fortinet Community Forum.

 

Problem Description:-

SSL VPN issue for mac user

 

Can you check whether the domain is being resolved with the correct IP address in MAC PC

Further please share below op:-

diagnose vpn ssl debug-filter src-addr4 <x.x.x.x>

diag debug app sslvpn -1

diag debug en

 

Let us know if this helps.

Thanks

Hi LD,

 

We are seeing "SSL_accept failed" error. Could you confirm if you are getting the certificate warning when using FQDN?

From MACOS 10.15 and above, there are new security requirements for Apple devices:

Hi Vimala,

 

The certificate warning only appears if you are connecting by IP. Connecting by FQDN does not appear.

When facing a "Network error. Cannot connect to VPN server" message with Forticlient VPN on Mac OS, there are a few steps you can take to address the issue. First, try clearing the DNS cache by opening Terminal and entering the command: sudo killall -HUP mDNSResponder. This can help resolve any DNS-related problems. Additionally, verify your DNS settings on the Mac and ensure they are correctly configured. You can try using alternative DNS servers such as Google DNS (8.8.8.8 and 8.8.4.4) or OpenDNS (208.67.222.222 and 208.67.220.220). If the issue persists, check if there are any firewall settings or security software on your Mac that could be blocking the VPN connection. Temporarily disabling such software or adding exceptions for the VPN might help. Lastly, make sure your Forticlient VPN software is up to date, as newer versions may include bug fixes and compatibility improvements.

The solution is to buy an ssl certificate since otherwise Apple devices updated to the latest versions of operating systems do not connect. We added a certificate to our Fortigate and now everything works fine. Thank you
