That’s curious, I’ve been changing my server’s DNS setting with no luck. I’ve just changed my client’s DNS (which was using my PiHole servers, pointed to OpenDNS) to now use Google’s directly. Now the client loads correctly. When I change back it fails.
So it appears a DNS propagation issue?
Yeah, OpenDNS seems to be what is my systems issue. Hope this gets fixed as I use OpenDNS for filtering 
Same problem for me. Changing to Google DNS resolves the issue.
Seems like an OpenDNS problem.
I was able to configure my router to send dns queries for *.plex.direct and *.plex.tv to google while retaining the usual opendns configuration for everything else so for now it works. Hopefully it gets resolved for everyone else soon.
I have been having this issue since last night. Have been using OpenDNS on a network level, but will try switching to Google DNS.
EDIT: Seemed to have done the trick!
@BigWheel I am going to send you a screenshot of the console log error messages and my Plex logs. Please let me know if there’s another issue at hand. For reference I’m trying to access my server remotely. Can do so from mobile devices, but not from Web or Android TV. Can VPN into my network and access the server directly (how I’m able to retrieve the logs).
My setup is also using Pi-Hole. I went into Settings - DNS and switch my ipv4 settings from OpenDNS to Quad9 (filtered, DNSSEC). After i made the change on Pi-Hole, i close my browser and reopen app.plex.tv with the new dns settings in pi-hole. I had to do that for each PC in my house using the link before switching back to OpenDNS.
FYI, mine is back up, using OpenDNS today.
might not have to switch DNS (and back) if flush cache
MacOS: in terminal.app
sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder
Linux w/systemd:
sudo systemd-resolve --flush-caches
Pihole:
pihole restartdns
Windows (command prompt as an admin):
ipconfig /flushdns
This also fixed it in my situation.
I’ve been troubleshooting this issue the past few days. I can confirm that opendns is the cause of the problem.
However, it is still a problem for me. If I set to cloudflare it works but after switching back to opendns and clearing cache it goes back to app.plex.tv is unable to connect to "scuro-server" securely
I checked blocked logs on opendns and I am not finding anything being blocked.
OpenDNS. Super frustrated. Troubleshooting all day, just started a few days ago.
Looks like it is resolved now for me on OpenDNS. I made no modifications and app.plex.tv is now showing my server.
Have the same issue.
Here are my logs.

i tried switching to opendns, i flushed my cache still no go.
the ■■■■■■ thing about all this is, i have my whole family and such that uses it. and bugs the crap out of me, giving me wicked anxiety because theyre depending on me for this. and im just like, about 3-4 times a day “its nothing i can do.”
Got rid of OpenDNS, moved to Google DNS, things back to normal.
I tried today with googles dns,
The Google Public DNS IP addresses (IPv4) are as follows:
8.8.8.8
8.8.4.4
The Google Public DNS IPv6 addresses are as follows:
2001:4860:4860::8888
2001:4860:4860::8844
didnt work.
Hello,
I got the same issue.
flush cache and reboot doesn’t work for me

thanks
@BigWheel I have exactly the same issue. Plex app works remotely and from home. Web app does not work (app.plex.tv) home and remote. I switched DNS, but that was not helping
What is the current fix? I am on the latest server version.
I just noticed this in the Chrome logs… why is it doing http ??
[Connections] Aborting connection test for <SERVER NAME> at http://<PUBLIC_IP>:32400/media/providers due to mixed content prevention
I got the same problem as many others. I’m getting no acces to my plex server outside of my local network. When I use the plex app on my ios device, there is no problem.
But when I’m in office I can’t get acces to my server from my browser. I also changed the DNS Server to google on my office laptop.
I also disabled the secure connections today for testing.
All ports, that er needed for plex are opened in my router.
The access worked some time ago and I never made any changes.
Is it a cert problem?
Send you my logs in PM @BigWheel
