Hello team

One of our Sub-tenants is not able to see list of extensions. While the Main Tenant is able to see all extensions including this tenant’s.

When connected, they see message on bellow screenshot

So far we have done bellow actions:

try clearing the cache:

/usr/share/vitxi/backend/artisan optimize
vitalpbx apply-firewall
/usr/share/vitxi/backend/artisan websockets:ssl-config
systemctl restart vitxi

No chance so far
