Certify The Web for Windows Server 2016 Essentials Access Anywhere

Hello community! I’m new to Certify The Web and was hoping somebody could help me understand: Can I use Certify The Web to create a SSL Certificate for Remote Web Access and VPN on my home server (Windows Server 2016)? All I’m trying to do is get around having to purchase a SSL Certificate every year simply to access my server/network remotely. I’m not hosting a website, so I think all I need is a DV for Windows Server (IIS). Does anybody have a tutorial on exactly how to do this maybe?

Thank you!!!

The app is free for the first 5 managed certificates, so that usually covers most people. Sorry I don’t have any experience with Server Essentials. You should start by requesting a certificate for IIS then see how you can script it to apply to other services/products.

Okay, thanks Christopher!

Since WSE2016 uses SSL for Remote Web Access, I’m pretty sure it will work as hoped.
I use WSE2012 and the RWA website runs happily under a LE certificate. I don’t use SSL VPN so can’t answer that one, but would be interested to hear your results if you try it.

This free guide will help you Get a free Let’s Encrypt SSL certificate for Access Anywhere and automatically renew it.

Hello,
I’ve set up our server using the very useful guide above but I still have to run anywhere access repair to get the vpn working again after a renewal. If I run the script (unaltered from the example script fro RDPGatewayServices) as a test from within Certify the Web it breaks the vpn so i think there is an issue in it for Essentials maybe?
Any thoughts?
Ps I am an enthusiastic amateur!

I’m not an expert in that I’m afraid but the default script probably doesn’t restart the service, so maybe you need to adjust that to restart the necessary services?

On a related topic I’m working on a new feature called ‘deployment tasks’ for the next major version, this will allow configuration of common deployment tasks such as this, in particular it will allow you to disconnect certificate renewal from the actual deployment (which you can defer for a maintenance window instead) : https://github.com/webprofusion/certify/issues/440

It sounds like you have the same issue as my WSE2016, using SSTP VPN.

When you update the certificate, the new certificate is bound correctly in IIS, but the SSTP VPN is still storing the old certificate hash. The symptom is that the SSTP VPN client connects, but immediately disconnects, and the client logs RRAS event ID 6 in its event log.

The solution is:

netsh http show sslcert
Note the changed hash for 0.0.0.0:443. This will need to be changed for the SSTP VPN listener (SHA1).

If no RRAS GUI (per WS2016E):
- Go to HKLM\System\CurrentControlSet\Services\SstpSvc\Parameters
- Alter the “SHA1CertificateHash” key from your new certificate (old hash should match Event 6 RASMAN error). You’ll need to type it by hand, paste doesn’t work.
- Restart RRAS service
- Test the new configuration

Thanks for this. Would this need to be done after every cert renewal?

@Shaunreynolds yes the cert hash will change after every renewal so you need to re-deploy it to anything that uses it.

Is there any update on this? I too have problems with Windows Server Essentials 2012/2016 and SSTP VPN stopping working after the certificate renews.

Due to the short certificate life, ie 90 days, it’s not ideal to have to manually intervene (and the best manual solution seems to be a server restart) as frequently as this compared to purchasing a certificate which could last for multiple years.

I do appreciate all the hard work that’s gone in to making the app - it’s a great thing, but this little niggle is a pain :slight_smile:

Hi David,

I’ll be honest I have no relevant experience with administration of SSTP VPN so I have to defer to the community to figure out the finer points of scripting certificate updates for that. Really supporting specific services like this is outside the scope of the app itself and more in the realms of scripting (which is usually custom). The assumption from that point on is that the users themselves know how to administer/update certificates for their chosen software components, which is not always going the be the case.

From my reading of the above thread the service may need a registry update with the new certificate hash then the service needs restarted, so that’s what you’d script. For direction here is a sample script from another user which may be helpful: https://github.com/webprofusion/certify/issues/447

Over time I do intend to add specific deployment tasks (with UI) to target common services and work has started on this but SSTP VPN is included yet.

I have the same issue as my Windows Server 2019 Datacenter, using SSTP VPN.
Two errors:
“Routing and Remote Access” service stoped.
And “RasSstp” lacks of ceryification for SSTP.

I’ll try the solution you gave here.

Thanks!

Confirmed that the script in the link does indeed work.
I copied the text and saved it on the affected machine as a ps1 file.
I then linked to it in the Post-request PS Script box and clicked “TEST”.

Confirmed that the registry entries in HKLM\System\CurrentControlSet\Services\SstpSvc\Parameters relating to hash values changed.
SSTP connections immediately before the script failed.
Attempts immediately after the script work correctly.

The only issue was a dialog box “Waiting for RRAS service to stop”. Presumably the machine was slow when stopping the service. It didn’t stop the script from running. When the script is called as part of the usual renewal process, I’m guessing the dialog will be suppressed in any. I’ll know for sure in 10 days.

Thanks to j0mbie on Github for the code.

Thank you very much! I am waiting for the next major version from you.:heart_eyes:

Thanks, next major version is likely a beta release in August, full release Sept/Oct.
