If another system service claims Port 443 before Veeam starts, the Veeam Installer will block deployment, or the VeeamBackupEnterpriseManagerSvc will fail to initialize. Step 1: Identify the Occupying Application
Which or process did the netstat command identify as the port owner? Share public link
VMware vCenter Server uses port 443 for its web interface. When both Veeam and vCenter run on the same server (though this isn't recommended), conflicts arise.
Run the following command to map network listeners to their active processes: netstat -anob | findstr :443 Use code with caution. If another system service claims Port 443 before

: Stop the conflicting service during the Veeam upgrade. While Veeam Support
Some users report disabling the conflicting service only during the Veeam upgrade, though the VBR console may still fail to work post-upgrade if 443 remains occupied. When both Veeam and vCenter run on the
Update the in the settings for each VM on every host to match the new port. For IIS Sites : Open IIS Manager and expand Sites . Right-click the site using 443 and select Edit Bindings .
Required Port 443 for Veeam Backup & Replication Is Occupied by Another Application
Step 1: Hyper-V Setting -> Replication Configuration -> Change Specify the Port from 443 to something else. Veeam B&R 13 Change Web Service Port 443 21 Nov 2025 — re-replicate the VM
If you change Veeam’s port from 443 to something else, remember to update all involved firewalls:
This usually indicates a Windows service like HTTP.sys is holding the port. Step 2: Resolve the Conflict
Some users have successfully completed the upgrade by temporarily stopping the conflicting application to let Veeam claim the port first. However, if the other application restarts and takes the port back, Veeam services may fail. :
Historically, Veeam relied on arbitrary, customizable high-range ports for basic control communications, leaving standard web ports clear. However, modern iterations of Veeam Backup & Replication rely heavily on the and built-in REST API architectures.
: Third-party agents or previous Veeam components might still be holding the port. Solutions and Fixes
