I was playing around with some SSL settings in Emby, and I managed to get this 'Secure Connection Failed' error which says:
An error occurred during a connection to emby.home.local:8920. PR_END_OF_FILE_ERROR
What is this error message trying to tell me? Is there any Firefox documentation where this error message is listed?

This error means that Firefox wasn't able to establish a secure connection and that all cipher suites failed (Firefox reached the end of the list).
Here are some thoughts about the cause:
The post says that you "was playing around with some SSL settings", so it is possible that you have specified some cipher variants that are not supported by Firefox or by the website you are trying to reach. Try to reset your settings to their initial state.
This can happen if you use a proxy or VPN or have other software that intercepts the connection and acts like a man-in-the-middle. Check your settings, and if using a proxy or VPN, try instead to connect directly.
It can also be the antivirus software. Try to disable or uninstall it.
Profile corruption is also a possibility. Go into
about:profilesand use "Create a New Profile" and set it to default. If this is working, export your bookmarks from the old profile and import them to the new one and continue using it instead.
I had this same problem using AWS LightSail. It ended up that port 443 was blocked by the server and I had to open the port up through the console.
I had this problem when I had a typo in the country name (UA instead of US) on an IIS Server, and FireFox returned the indicated error (egg on face).
The error is often not related to the browser. In our case it was also not a configuration thing of nginx, but a wrong setting of the firewall. So logically, when I say that often has nothing to do with the browser, server-side and not client-side. Accordingly, it was not a proxy or VPN.
1I have a paid VPN service and I use several add-ons. All are designed to prevent tracing back to my actual IP Address, remove tracking cookies, prevent auto-install trojans or viruses and prevent any other known hacking methods. I find that when the site I want to visit cannot trace back to see my actual IP address, it gives an error code "Proxy end of file error" because it was bounced to more than one IP address. I will then disconnect the VPN, keep all the other add-ons active, and make sure to connect directly to the site I want. When I'm done, I logout, close the browser, turn the VPN on again and re-launch my browser.
I noticed that simply switching to another VPN server or opening the URL in chrome (webkit) can fix the error.
Had this issue when using Surfshark VPN while working with virtual machines in VMware Fusion.
I could not access the AWS console or login into GitHub
Tried a lot of things to fix it such as:
- Reinstalling my VMWare
- Setting a new VMWare virtual machine
but none worked.
Here's what worked
I noticed that this error started after I updated the Surfshark VPN
Changing the connection protocols resolved the issue.
- Open the Surfshark application
- Click on Settings
- Then Advanced
- And lastly, Protocol. Here, you will find all of the available protocols, including IKEv2, OpenVPN UDP/TCP, WireGuard, and even Shadowsocks.
So for me, I changed it from WireGuard to IKEv2, and that solved it.

That's all
