I am the only one of the team who could not connect to VPN. Encountered error message is "Status: Server did not respond properly to VPN Control Packets". Date and time is synchronized Azure VPN Client is allowed on firewall Tried updating WAN Miniport adapters AzureVpnCxn.log AzureVpnClient.log

@Surio, John Dye , Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well. Is this the entire error message? Was there a Session State present in the error message? When you say only you are facing this issue, Is the issue isolated to a single remote PC or is it reproducible with every remote PC? Is this issue happening with a single user or is it reproducible with every user? i.e., the above will help us isolate if this a user issue or device issue I would suggest you to download the VPN Configuration once again and import the file (not manually fill the configuration) into the Azure VPN Client App and try again. Follow : Configure the Azure VPN Client - Microsoft Entra authentication - Windows Your error seems to be related to a mismatch in ServerSecret Cheers, Kapil

Hi @KapilAnanth-MSFT ,

Thank you for your quick response. As per the questions, here are the answers.

The entire error message is "[Error] Dialing VPN connection vnet-cfx-connectivity, Status = Server did not respond properly to VPN Control Packets. Session State: Reset sent" as taken from the log file.

For the issue, I out of 5 members of the team, I am the only one who experienced this kind of issue. Though they are located in a different region. Since this only happened to me, we could not reproduce it to other members.

I will try your suggestion on reinstalling the application. Thanks

Hi @KapilAnanth-MSFT , apologies for the delay in response. Had trouble contacting local IT representative to reinstall the application. I was able to reinstall the application but still encountering the same issue. The exact error message from before is what I am getting.

@Surio, John Dye ,

Per the logs you shared, it looks like your login was successful.

Whatever is causing the issue, appears to be at the device end.

To troubleshoot further, we will need a specialized 1:1 session, where a support engineer can have a screen share session to pinpoint the issue. If you have a support plan you may file a support ticket, else please do let us know, we will try and help you get a one-time free technical support.

Cheers,

Kapil

@Surio, John Dye ,

After further troubleshooting, it appears the issue is isolated to an internal application blocking the traffic.

You informed us you will be working with your team to mitigate this.

I am glad you were able to arrive at the root cause.

Thanks,

Kapil
