Can't authenticate or sign in to server, or plex.tv

What do you mean by hosting location? I will call CenturyLink soon, thanks for the input and I’ll come back with an update.

so

this is frustrating and I don’t understand it.

I called CenturyLink and we still haven’t technically solved the issue but the site and server work now. I can access plex.tv, app.plex.tv, and forums.plex.tv and sign in without issue.

We were going through all the regular internet rigmarole (“did you reset your router”“did you restart you computer”) and I eventually got through that I’d tried all that weeks ago AND ALL THESE OTHER THINGS (DNS, NAT, firmware up- and downgrades, firewall, etc) and got them to agree it was a very weird issue. Then he had me turn my VPN back on which was counter-intuitive to me, I thought for sure that wouldn’t change anything since Plex is notoriously strange behind VPNs.

Now I can login to everything and sign in on my local server.

I don’t understand why but naturally he said “problem solved!” and sent me on my way without uncovering the underlying issue.

I use PIA and I think they use their own DNS servers (PIA DNS) but that is all I got.

But now I can access and sign in to everything locally…but nothing’s available remotely. So I’ve switched one problem for another. But I think that’s a different post, maybe? I don’t know. Kind of a win/loss situation, I guess. Does anyone have another thought about why turning my VPN on magically fixed the authentication handshake?

I do not run a VPN, so I’ll be of limited help troubleshooting any VPN issues.

That written, where is the head of the VPN tunnel - PMS server, router, etc.?


Follow up on traceroute & ping.

Many hosting providers and some ISPs block traceroute and ping, so when they do not work, it is not necessarily a bad thing.

Since neither of us can ping/trace plex.tv, yet I can still login, it indicates the blocked pings/traces are not a problem.

app.plex.tv and forums.plex.tv are in different locations and I was able to trace to them. That’s why I mentioned those in my post. It is good you can reach app.plex.tv. It means you can resolve the addresses and your ISP is not blocking the path.

I did a bit more testing. I can traceroute to plex.tv if I use TCP port 443. Windows tracert uses TCP port 80, and unfortunately, there is no way to change the port number.

The Linux command structure is: traceroute -4 -T -p 443 app.plex.tv (on my Synology NAS, anyway).
-4 = use IPv4, not IPv6. Not needed if your system is IPv4 only.
-T = use TCP (Linux, unlike Windows, defaults to ICMP)
-p 443 = use port 443 (https), instead of port 80 (http)

So now with the VPN up, I can reach the forums, the app, and I can sign in to my server.

However, it’s no longer available remotely. I tried the bat file here after putting in my gateway and running as administrator but it doesn’t seem to work and I’m not a networking guru.

Has anyone ever run into plex being geoblocked before? This is all very, very strange.
