Checked the issue of FSRI Payroll with FSDM, they are receiving "Connection test failed" error. Validated the connection of the IP address, tested all the IPs of bio that they are accessing. Found out that the issue is the connectivity of the biometric, when pinging their IP it was RTO while other active IPs can connect to the FSDM. Coordinated with Sir Dennis and Ms. Belle for checking the biometrics' connection, this is now okay.
