Google can tell you what a Fritz box is 
A router from a German company, very popular here.
The FritzBox is a fairly sophisticated router produced by a German company and mainly sold and used in Germany. It can also work in other countries and I specifically bought one to use in the UK. I like the very clear user interface and the flexibility that allows for almost anything you want to do with a router. Caveat: itâs German only, so your mileage may vary
Iâm very curious about the DOCSIS 3.1 issue. This is a protocol for cable TV. The FritzBox itself does not support cable TV. You would have to have a cable modem in front of the FritzBox and the protocol used in the modem should be completely transparent to the FritzBox.
Plus this issue (if it is the same issue indeed) ONLY affects the movie path in Plex MediaServer. The TV Shows are completely unaffected. It is either an issue with the API where PMS pulls the images from (does the iMDB provide such an API?) or it is an issue within PMS that prevents it from properly processing the images.
The fact is that it ONLY affects PMS installed on Linux, as my other installations (Mac, FreeNas) work absolutely fine.
So my gut feeling is itâs something within PMS, some incompatibility with the Ubuntu host.
@Coxeroni I wasnât asking. I just just providing the anecdote that Fritzbox has nothing to do with the issue as far as I can see, as I donât have one.
Specifically, the error message I got was
[Errno 104] Connection reset by peer whenever it tried to retrieve images from the agents.
Not necessarily. There are dedicated cable fritzboxes with the modem built in. They are affected, modem in bridge mode followed by a Fritz box router are not affected.
Please just use a VPN and refresh metadata. Many people in this topic have the same reason, because in Germany we had a significant increase in CableTV users.
I checked my two Plex servers, one running on a Synology NAS (Linux) and one on Windows. The Servers had different server versions. And I didnât do anything, just installed the new Fritbox 6591 and my home isp connection was switched from Docsis 3.0 to Docsis 3.1. And afterwards I had the problems. The known problems are Movies are correctly found, the metadata text is correctly loaded, but the metadata images/covers are not displayed.
I think itâs about the Docsis 3.1.
The only workaround for now is to use a VPN. I can recommend perfectprivacy, but I am sure other VPNs will also work. Please just test it, and Iâm 100% sure it will work while using it.
Well, what can I say: the irony 
As mentioned before, my setup is a Ubuntu machine behind a Huawei mobile broadband router, no FritzBox involved. In this configuration Plex does NOT load the movie posters, no matter what I tried.
So I followed DomiBaseâs advice and set up a VPN connection.
As it happens, this VPN is served by a FritzBox 7530, fed by a cable modem. (FritzBoxes have a built-in VPN server, really easy to set up).
And lo and behold, Plex is loading the movie posters! Swiftly, no delays and all of them.
(This is all within the UK, no other countries involved).
Riddle me that.
This works just fine for me too, so no riddle there. It is only the cable version of the Fritz box that seem affected. Dunno what is wrong with your connection in the first place.
In my Plex library, a bunch of movies that used to have posters seem to have âlostâ their posters.
I went through them all and manually chose new posters. The problem is that the posters are not being rendered. If I click âeditâ again, it remembers the choice I made before, but it doesnât render on web nor players.
Is it this same issue?
I have just noticed this exact issue. For me all posters were showing correctly, but when I update a poster, it doesnât show (just a black rectangle). When I click Edit and go to the poster section it shows the correct selection, but it doesnât render.
Just found this thread searching this exact problem. I moved my movie library to a new, larger drive and have been updating, adding all the extras I skipped before. Mostly itâs fine, but when Plex grabs the wrong poster (not matching the copy I have), I ran into the blank box trying to change it.
I did the HTTPCookies fix suggested way up near the beginning of the thread. I have to refresh metadata on the individual movie, but it works. Iâm on version 1.19.4.2935.
I have just noticed this exact issue. For me all posters were showing correctly, but when I update a poster (to select a new one, not the default one), it doesnât show (just a black rectangle). When I click Edit and go to the poster section it shows the correct selection, but it doesnât render.
To add to this, even after I refresh metadata the problem persists. It still just shows a black rectangle.
This is definitely a bug.
I am also having this issue. A bunch of posters got garbled last night and show up as blank (donât render at all).
Edit: sometimes refreshing metadata works, sometimes it doesnât. The posters seem to render sometimes too, and other times they donât. Currently 2 are not rendering in the browser but work on the windows app.
Edit 2: The images themselves are returning 500 errors when being requested (e.g. https://>address-here<:32400/photo/:/transcode?url=/library/metadata/81194/file?url=metadata%3A%2F%2Fposters%2Fcom%2Eplexapp%2Eagents%2Eimdb_3a4e6130c07c37d890a82e88cd8f08dbcd23ad18&width=134&height=201)
Hello,
I am running Plex on a TNAS server. I had an issue the other day where my modem assigned the TNAS a new DHCP lease. I corrected that and my other network issues, however, I found after refreshing my metadata all my movie posters were blank. I eventually, broke down and simply removed the library and reinstalled it. This brought back all the poster images. I downloaded a new movie to the NAS and after about two hours, I noticed the movie I downloaded still did not display the proper poster image.
I am attaching the server logs if someone can see whats going on.
I appreciate the help.
