Comodo SSL - Local Network - ssl

So I've set up a Comodo SSL certificate which is working fine:-
https://infinityfinance.net/
This was configured on the Windows 10 machine using IIS. This works perfect and I can see it's secure but it doesn't seem to work on the local network for some reason.
I just get a certificate warning and can't access the web site, this is when I am trying to access the web site via https://infinityfinance.net/ and not localhost, please advise.
Thanks in advance.
These are the errors when accessing locally:-

Using an External CA for SSL Certificate for interlal IIS website

I have a website built and running on IIS / Win 2012R2, its only accessible within my local network and will never reach the outside world.
Currently, I'm using a self-signed SSL certificate that I have installed on all my windows machines, no problem!
I now need to get the website to work on Android 7.7 tablets, without the chrome browser complaining about the use of a self-signed certificate. I'm not able to install my Self-Signed certificate on these devices so I need to use an online CA.
The question is, how can I link an online CA to our internal website? The key issue being I don't have a domain, the path to access the website is https://servername/website
Is this even possible at all?

How can I access a self-signed webserver using SSL but from another computer on LAN?

Problem: Since Chrome updated a while back (version 58?), I'm not able to access my computer's development Express web server with HTTPS from a remote machine on the same private LAN.
I have created a self-signed certificate on the server (my laptop), and it works great from the same machine via https://localhost:8383 (the local SSL port).
In the past I could bypass the warning on a remote machine on the same network but it has stopped working.
I've gone through the steps of creating a local secure DNS server on my own router with DD-WRT, and self-signed a new certificate with SAN so I could use a DNS host name to access it without specifying an IP address.
I'm able to get to the page after bypassing the message that warns the site's SSL certificate could not be verified. But that's not good enough because while the site will load, the underlying websocket service I'm using on the same port does not work, and so the application loads but is broken on the remote machine. Still works on the local machine because the certificate is valid.
It seems the issue centers around Websockets within Express.
Any guidance would be greatly appreciated! This is a strictly secure environment that's meant to be used on a private network and it makes no sense for me to spend a bunch of money on a public certificate if that even matters.
Thank you.
It appears that the issue is with mobile Chrome and Safari on IOS -- I can get untrusted SSL certificates to work with websockets from another computer on the same network with the latest versions of Chrome and Safari. But on IOS (ipads and iphones), the page will load after being prompted, but Websockets FAIL to function whatsoever.
I've found a couple other people finding this issue.
My workaround for this problem was to revert away from SSL for my private network and completely avoid self-signed certificates.
In a private environment this is OK.

Using ssl with localhost with asp.net mvc 5 on VS2015

I'm trying to test my website locally using SSL with IIS Express. It has the following properties set:
SSL Enabled set to 'true'
SSL URL is set https://localhost:44354/
But whenever I open the https address, I get the following error:
In "Microsoft Edge":
In Google Chrome:
I've read article after articles, including some on SO but to no avail. I've tried the following:
I've deleted my IIS Express Development Certificate
I've repaired IIS Express 10 via the Control Panel
I've removed the localhost certificate I had created manually.
I've added <binding protocol="https" bindingInformation="*:44354:localhost" /> to the bindings section the applicationhost.config
I've stopped and restarted IIS Express.
Some suggest to change the port to 443 but my SSL URL is read-only in .NET IDE.
Some articles I've read:
Running IIS Express without Administrative Privileges
How do I fix a missing IIS Express SSL Certificate?
IIS Express — Getting SSL to Work
and many more...
Any help would be greatly appreciated.
Thanks.
I finally figured it out by following this article How to trust the IIS Express Self-Signed Certificate but a few additional steps:
Export IIS Express Development certificate to a local from. This certificate can be found in the Server Certificates section in IIS 10.0.
Open the Certificate console by calling mmc.exe certmgr.msc from File|Run.
Delete all instances of localhost under the Trusted Root Certification Authorities|Certificates.
Import the newly created certificate. You will get prompted with the following:
Once imported, I went back to Asp.Net MVC 5 project, recompile it and ran it. When I ran it, I got prompted with the following:
This is when I knew I was on the right track as this was the first time I had ever seen this prompt! Click Yes, and now this prompt appears:
And click Yes on this prompt as well. Your project will then launch the relevant browser.
Go to the https address defined in your .net project, in my instance, https://localhost:44354/, and you will now see the padlock displayed in the address bar to indicate that it is a secure site:
Most of these answers were already available in different answers provided on SO but the points that were missing or that I missed were that I had to export my IIS Express Development certificate, delete all localhost entries (which I had done) and then re-import this certificate. Once done, .NET detects the change and you get prompted accordingly.
Anyway, I hope this will help others.
Self signed certificates need to be trusted or browsers won't accept them. You can easily use Jexus Manager to configure that,
https://www.jexusmanager.com/en/latest/tutorials/self-signed.html#to-trust-self-signed-certificate
While if you prefer manually, you can import the certificates to the Trusted Root Certificate Authority store in Windows.
Learn more about SSL, certificates, stores and so on (Google each of them and learn them thoroughly), so that next time you really understand what is the culprit before trying so many irrelevant things.
Jexus Manager also has an SSLDiag feature to identify potential issues,

But you need to know enough so as to interpret its output correctly.

- CA SSL config issues with RESTCOMM

First to explain our application, its as follows...
1)We have one UBUNTU server where we are running Apache Tomcat and also RESTCOMM.
2) We have two application war files. One is the main application and another is a customized OLYMPUS Application to facilitate WebRTC calls. Now our Main application has a menu option which when clicked will load customized OLYMPUS Application into the browser and facilitates the WEBRTC for users.
3) We have tested this properly by using Self Signed Certficate and all is working well. But now we want to use CA apporved SSL Cert.
4) for this we have bout SSL CERT from GODADDY and for this the CSR was generated for Apache and then by using that CSR we downloaded the SSL CERT for Apache and configured by following the same process of how we configured Self Signed Cert.
5) Our main application is working well with the newly installed CA SSL Certificate. But when we try to load the customized OLYMPUS application we are getting the following error ...Web socket connection to ‘wss://>:/’ failed: WebSocket opening handshake was canelled.
We are able to get all working with self signed cert, but we are stuck with this problem when we use CA Approved SSL Cert from GO DADDY.
Request your suggestions pls.
Thanks in advance

You need to configure Restcomm to use SSL Cert as well since the Websokets secure connection goes directly to Restcomm. Which method are you using for runnning Restcomm, using the zip file or the docker image ? Also which version of Restcomm are you running ?

https stops working after site publish

I am working on Windows Server 2003 (IIS6), which has two asp.net sites running in seperate app pools. One of the sites has an ssl certificate installed and was running fine on https. The other site has no certificate and does not require https
The problem I have is that when I publish my app from vs2005 to the site with ssl the https urls stop working and I can only use http. The error I get is as follows
From Google Chrome: Error 104 (net::ERR_CONNECTION_FAILED): The attempt to connect to the server failed.
From IE7: Internet explorer cannot display the web page, could be unavailable, dns is not reachable etc
The strange thing is the first time this happened, https eventually became available but I don't know what triggered the availability but when I published an updated assembly to the bin folder of the site which does not require https, the OTHER site became unavailable on https again
Help much appreciated!
UPDATED: Thanks for the suggestions but it turns out that the firewall was not open on the ssl port
Check if the firewall port for SSL (443) wasn't accidentally closed 443. ;-)
If both webs use the same IP address, make sure, that only the web with the certificate uses the SSL port 443 (first property page). The input field should be empty for the insecure site.
If that is not the problem, you could try to debug stopping the web without certificate and restart the web server.
