How do you access the About/checkup page now that it's restricted to authorized IPs.

Problem reported by David Feuer - 1/15/2026 at 8:52 PM

Resolved

OK, I'm missing it. To be fair it's 10:45 at night and I have been up since 6AM.

But with today's release and the blocking of that page. How do I add an IP that can get to it.

Thanks,

Dave

Same here on two servers after update to build 9511. Just why?

I don't have an About/Checkup page on my installation, but the Settings/Troubleshooting page is no longer accessible - it returns a 403 Forbidden error when trying to access it. There is no way to define an authorised IP address to access this page.

I logged this as a ticket before seeing this thread and was told that the following was now the case:-

Access to this page is now limited to:

Browsers accessing the server from the same local network (private IPv4 ranges), or\
Authorized internal IPs used by SmarterTools

So basically, you only have access to this page if you are running your SmarterMail server on the same private LAN as your client PC or are on the SmarterTools network.

I have objected to this restriction as there is no way I can meet these restrictions as my server is housed in an external server centre and I use that page every time I upgrade to a new version to check that all functionality is working as expected.

I have suggested that the restrictions are wrong and that that page is of valid interest to all SmarterMail server admins and should be available to any of the admins listed on the Setting/Administrtors page, irrespective of IP address. I'm happy to accept that there is no reason I can think of why Domain Administrators or Users should have access to that page.

That proposal has now been "escalated this request by adding it to the product backlog"

Checked and if you are on the server itself

localhost:17017/About/checkup

does work

The /About/Checkup endpoint will be available as it normally is from localhost and internal network addresses. You may need to add a binding for your server's local IP address in order to reach the web interface from another computer on the network as well if you modified the default bindings.

I'm curious how the community uses/accesses this page.

Are you logged in as a system admin and then navigating to Settings -> Diagnostic to view the checkup page?
Do you have the checkup page bookmarked and so you're accessing the page via an unauthenticated session?
What information on that page is important to you?

Remember, we needed to not show this information publicly so knowing how system admins are using/accessing the page and what info they need can help us come up with a better solution. Please provide feedback.

@Larry, only accessed the page using the system admin. Would not have expected that the page is viewable without authentication.

Just out of curiosity on this one, but can we have the option to expand this functionality? there are other sections within Smartermail that are probably considered more important that i would love to be able to lock down to certain IP addresses or even local network / host only. But it would be an optional setting not a blanket forced option.

@Larry - only accessing this page whilst logged in as the System Administrator and from the Settings/Diagnostic menu.

I use the information to confirm that the server is up and running, DNS resolution is happening, licensing server can be contacted, .NET versions are properly installed etc. Basically I look to confirm that everything has passed the diagnstic check.

@Larry, only accessed the page going through the system admin. We never thought about accessing it any other way.

I usually took a look at it after every install just to be sure and then only looked if there was some sort of issue with the server to see if that page showed anything.
