 | Causes | Recommended actions |

 | **Vault credentials aren't valid** <br/> <br/> Vault credential files might be corrupt, might have expired, or they might have a different file extension than `.vaultCredentials`. (For example, they might have been downloaded more than 10 days before the time of registration.) | [Download new credentials](backup-azure-file-folder-backup-faq.yml#where-can-i-download-the-vault-credentials-file-) from the Recovery Services vault on the Azure portal. Then take these steps, as appropriate: <br><br>- If you've already installed and registered MARS, open the Microsoft Azure Backup Agent MMC console. Then select **Register Server** in the **Actions** pane to complete the registration with the new credentials. <br> - If the new installation fails, try reinstalling with the new credentials. <br><br> **Note**: If multiple vault credential files have been downloaded, only the latest file is valid for the next 10 days. We recommend that you download a new vault credential file. <br><br> - To prevent errors during vault registration, ensure that the MARS agent version 2.0.9249.0 or above is installed. If not, we recommend you to install it [from here](https://aka.ms/azurebackup_agent).|
-| **Proxy server/firewall is blocking registration** <br/>Or <br/>**No internet connectivity** <br/><br/> If your machine has limited internet access, and you don't ensure the firewall, proxy, and network settings allow access to the FQDNS and public IP addresses, the registration will fail.| Follow these steps:<br/> <br><br>- Work with your IT team to ensure the system has internet connectivity.<br>- If you don't have a proxy server, ensure the proxy option isn't selected when you register the agent. [Check your proxy settings](#verifying-proxy-settings-for-windows).<br>- If you do have a firewall/proxy server, work with your networking team to allow access to the following FQDNs and public IP addresses. Access to all of the URLs and IP addresses listed below uses the HTTPS protocol on port 443.<br/> <br> **URLs**<br> `*.microsoft.com` <br> `*.windowsazure.com` <br> `*.microsoftonline.com` <br> `*.windows.net` <br> `*blob.core.windows.net` <br> `*queue.core.windows.net` <br> `*blob.storage.azure.net`<br><br><br>- If you're a US Government customer, ensure that you have access to the following URLs:<br><br> `www.msftncsi.com` <br> `*.microsoft.com` <br> `*.windowsazure.us` <br> `*.microsoftonline.us` <br> `*.windows.net` <br> `*.usgovcloudapi.net` <br> `*blob.core.windows.net` <br> `*queue.core.windows.net` <br> `*blob.storage.azure.net` <br><br> Try registering again after you complete the preceding troubleshooting steps.<br></br> If your connection is via Azure ExpressRoute, make sure the settings are configured as described in Azure [ExpressRoute support](../backup/backup-support-matrix-mars-agent.md#azure-expressroute-support). |

This tenant id is unique per Azure region. You can find the tenant id by opening the vault credential file and locating the `<AadTenantId>` element.|
 | **Antivirus software is blocking registration** |  If you have antivirus software installed on the server, add the exclusion rules to the antivirus scan for: <br><br> - Every file and folder under the *scratch* and *bin* folder locations - `<InstallPath>\Scratch\*` and `<InstallPath>\Bin\*`. <br> - cbengine.exe   |
