Server Version#:4.147.1 Player Version#:1.42.1.10054 Have setup a lenovo thinkcentre with the latest ubuntu version. Have setup filesharing with my pc which works just fine, ethernet works just fine connecting to the internet, however when i try to setup new libraries, it can’t see the new directories I’ve made, or the media files inside them. I’m also having issues where remote access randomly deactivates after refreshing the browser connection.

For the remote access deactivation I have found that setting it to manual and putting in the same IP it normally uses (I think 32400) seems to resolve it. I am having the same core component issue, however, after just installing it on a laptop I have used as a server before with beefy enough stats to run it. I have run server on much less. Not sure what the deal is. ---

Also, I forgot to mention: did you forward the ports on your router for plex server? ![image](https://global.discourse-cdn.com/plex/original/4X/8/e/1/8e135f1f237281854927bb6376d502eece3f15e6.png) ---

I have it port forwarding through my router yes. On my personal desktop I have another server, one I was trying to move to the external. That one says its not sharing with the internet… but I have a friend in another state who’s capable of accessing it. ---

I refuse to update my server and apps until the dust settles on the new experience rollout. There’s too much internal firefighting happening and things like this are usually the result. ---

All, we are aware and are looking into the multiple reports of this issue. Thank you for the feedback here. I have a few questions as I am unable to replicate, so anyone experiencing this that can provide more information would be helpful: - what URL are you experiencing this issue against? Localhost? specific ip address? app.plex.tv? - we have a few screenshots of the error message itself, but it is unclear from the reports what other actions are available. Is this error clearable? Are there other actions that can be taken once it is cleared? Are all left-nav functions blocked due to the error? Thank you all again. We will provide an update as soon as we have more information. ---

We still in testing internally, but based on the times we have been able to replicate this looks a bit like an issue in one of the elements that is trying to be drawn on that screen in the web client and nothing more.
