Hello,

I am a bit lost on this one.

I have suitecrm install on my own server ( (unbuntu 24.04). It is accessible from anywhere in the world, including my local network, using its dedicated domain name.

However when I am connected the server network with my providers VPN (IPsec/IKEv2 (strongswan)) , I have a NS-ERROR-CONNECTION-REFUSED in my browser (firefox) network.

I can ping the server no problem. Firewall is disabled.

Subnetworks of local, server, and VPN are different.

I did not find anything relevant in the Apache logs, neither the Suite CRM logs.

Any help woul be welbomed

Check what IP your SuiteCRM hostname resolves to over VPN

nslookup your.domain.tld

Confirm Apache is listening on 0.0.0.0 (all interfaces) and not bound to a specific address

sudo ss -tlnp | grep ‘:80|:443’

Try

sudo systemctl reload apache2

Check if ufw is off and empty

sudo ufw status

Check site URL

‘site_url’ => ‘http://example.com/suitecrm’,

Hello,

Thank you for your help.

At the end of the day, my VPN does not loopback.
I had to create new hosts in etc/hosts/ on the user computer pointing the domain name to the local address.

With the help of an AI (because I am a noob), I created a deamon that checks if the VPN is active, and if so it adds the host, if not it removes it.
