Symptoms

After upgrade to OA 7.x switch to Billing does not work.

Cause

OA was successively upgraded from 5.x version to 6.0 and then to 7.0. In OA 5.x Billing used the port 443 to access its panel. Starting OA 6.0, the port 8443 was introduced, however, environments, upgraded from 5.5 was still using the port 443 - please see more details in the OA 6.0 Firewall Guide.

Since OA 7.0, UI nodes require the port 8443 to be listened by Apache on the Billing application server.

Resolution

  1. Go to the Billing application server
  2. Edit the file /etc/httpd/conf.d/ssl.conf.inc and copy the whole configuration of the virtual host <VirtualHost *:443>
  3. Add the copied configuration to the end of the file /etc/httpd/conf.d/ssl.conf.inc replacing the port 443 with 8443 and save the file

  4. Restart Apache:

    # systemctl restart httpd
