Emby suddenly stopped working.

It comes up on Windows inside the home. Remotely, it does not.  Neither through the Android app or Windows. 

What about android inside the home?

[Zenith Media 4]

Yes, in the house, android works. 

[Zenith Media 4]

Doesn't work.

What doesn't work? 

Have you gone through all the various steps for setting up and enabling external access from the page linked above? - it's not automatic...

Paul

[Zenith Media 4]

Yes. I have. I just doubled checked the emby settings and eero settings.

[Zenith Media 4]

I checked it by turning my wifi out of my phone and tried to login to the server. 

[pwhodges 2019]

If you run a port checker on your PC, does it say your address is what you expect, and does your Emby port show as open?

Can you see your Emby machine and port if you use a scanner on your phone?

Have you checked that your ISP has not put you onto cgNAT?

Is the eero your router (I thought they just made wifi equipment)?

Have you opened ports for Emby in your router manually? or are you relying on uPnP for that, in which case, is it enabled in the router, and is the Emby plugin for it enabled?

You are giving us the absolute minimum information, thus making it very hard to help you.

[Zenith Media 4]

Giving information as I know it. Went through the emby help steps for external network.

uPnP is enabled in both.

eero is a router.

What do you mean by scanner on the phone?

eero doesn't have a web interface, it is app base. 

[Zenith Media 4]

But, I do have a mesh system connected with the eero, different brand. Is there a way to maybe do it through there instead?

Reviewing the thread, I note that you state that external access hasn't worked for a couple of years.  To my mind this makes it more likely that either there has been an IP address change that slipped past you , or that you have indeed been put behind cgNAT by your ISP.

How do you access you server externally - do you use your WAN IP address directly, or do you have a domain name (maybe from a dynamic DNS server)? Have you checked for cgNAT?  If your router tells you that your WAN address is 100.etc (more detail is then needed to confirm), or in any "local" address range, then you are.

If you go to a website like https://whatismyipaddress.com/ do you get the answer you expect (i.e. does it match what your router tells you, and what Emby shows in the dashboard)?

Using a site like https://canyouseeme.org/ does the port you use for accessing Emby show as open or not?

You mentioned that Plex continues to work.  Note that Plex has a built-in mechanism for getting around cgNAT - this involves going via their servers, so Emby does not replicate this so as not to compromise your privacy.

Paul

When it was working, I used the emby app to login. Now, I have tried the app and web browser and both do not work.

 https://whatismyipaddress.com/, yes it matches what is shown in the emby dashboard and main router.

Error: I could not see your service on  https://canyouseeme.org/  This the message from that website.

Oh okay, I always wondered why Plex is more simple connecting remotely. 

[pwhodges 2019]

OK, so if it's not cgNAT, then it pretty much has to be the port opening/forwarding.  What does your router tell you about its status?  For instance, does it tell you if ports have been opened by uPNP?  What happens if you try to open the required port manually?

I know nothing of this router, so it's between you and its user guide, unless someone else here knows it and can give advice.
