If it is your firewall, it is best to exempt your Plex server from being blocked. Never disable the firewall protecting your network from the Internet. If you have any of these active on your network, or Plex server, then try adding an exemption for your server, or maybe disable the blocker until you determine the cause. There are a number of reasons that your server can't connect to a website, including security software, firewalls, network ad-blockers, etc. Navigate to sites such as The Movie Database to verify the server can connect. If the first two options don't resolve the issue, and you know that movie posters exist online for the movie, check to see if the Plex server can also access the sites. Try using a different agent to see if it can download the correct movie poster. For example, instead of using the Plex Movie agent, you may be using the Personal Media agent. If you changed the agent used to gather metadata, then you may want to verify the agent can get the correct metadata. A third choice would be that you can also do both. In this case, you have two choices: add a poster to the site, if possible, yourself, or manually add the poster to your movie in Plex. The site that Plex uses to get the movie posters may not have a poster for that movie available. Double-check the movie file name and try to refresh the metadata again. If the movie you added doesn't follow the movie naming conventions, then Plex may not be able to find the correct poster for it. The sections below list the reasons as well as some solutions to resolve the issue. There are several reasons why this is happening. This isn't too common but can be frustrating to figure out why the posters aren't displaying. After adding movies to your server you may have an issue with the movie posters not showing up in Plex.
