Azure Virtual Network Gateway connection in failed state but working

Hello,

I setup my S2S VPN few month ago, connection is working, but I now notice in the portal, the connection is in failed state. I don't know if it has somehow any impact on performance or availability of our services, but it is still quite annoying to have this alert even though everything looks ok to me.

I tried already to reset the tunnel to switch from one gateway instance to the other, but it didn't help.

Does anyone have ever encounter a similar behavior ?

thanks!

Greetings,

Did you try resetting you VPN gateway in this case? If not, you can give a try. Resetting an Azure VPN gateway is helpful if you lose cross-premises VPN connectivity on one or more Site-to-Site VPN tunnels.

Note: When you reset the gateway, it reboots the gateway, and then reapplies the cross-premises configurations to it.

Here Is the article that describes about steps that must be placed before resetting a VPN gateway.

Hello,

yes, I already tried resetting the VPN gateway, but it didn't help.

Also, I check the gateway healthprobe and I do receive a successful response...
https://docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-troubleshoot-site-to-site-cannot-connect#step-7-verify-the-azure-gateway-health-probe

I don't have any UDR or NSG on the subnet where the route based policy gateway is deployed...

Had the same issue, portal status was restored using the following steps (from MS support):

Link :https://resources.azure.com/ and follow the steps as:
Step 1 >>Login into the subscription id>>Resource Provider>>Microsoft network.
Step 2>>Go to the VPN Gateway>>Connection .
Step 3>>Choose Read/Write>>Edit the Provisioning manually to Succeeded State>> Put.

However root-cause (why has the state become failed is still unkown.
