It really would be helpful if those testing this while in Beta could see our logs so we could troubleshoot where this might be failing rather than having to wait for @justin to dig through logs for those with issues like he has been.
This so much! I really wish I could see the logs, so I can see exactly where it’s messing up or if it’s even correctly running or anything (as currently it just feels like it’s not doing anything at all) without having to rely on other people to do it for me, so I can see if it’s something I can solve or not.
welp I’m over it, I’m disabling this as it just continues to not work for me and I guess I will try again in a few years when this will hopefully be out of beta stages.
Nearly every scan that it has actually done (which was only 5 in total and I’ve had this thing running since August 26th) were ones I initiated manually (and half the time initiating a manual scan didn’t work either), only 2 of those 5 were ones that was automated instead of manual.
And while yes I only had this thing running to add items to my library, I’ve added plenty of items in both my tv shows and movies plex libraries between the time I started using this and now that it just never seems to scan or like the last attempt it did were it actually did a autoscan it screwed up and ended up adding wrong items to my library which I ended up having to revert.
That’s fine, but as previously mentioned I have other tasks and can’t reactive in real time to plex sync issues. The latest posts were also over a weekend. My plan was to look at your account specifically this week and see what I could find.
I would need specific examples of this. I use IDs to match things and in general that is super accurate. If not, it could be Plex not having the IDs I expect and it instead is revering to a title based match. A specific example would be needed for this. That’s fine if you’ve moved on, but just general info that is helpful for others to dive deeper into metadata matching issues.

I’ll re-enable the setting again and add some more stuff to my plex today so you can do some testing over the week.

I can’t remember every movie that was in the one I had to undo (it was sync ID 1709000 if you can look into it more than I can) as it no longer shows what the items were that was mwatched once the undo has been done, but I remember one movie at least that was mismatched, I have the movie Outbreak in my plex library which is already marked as in my library on here (PlexTraktSync did the previous mark back on the 2nd of August, but I was hoping to start slowly shifting away from PTS), but the sync that happened back on the 5th of this month ended up also randomly going and marking this other movie Outbreak as being in my library for some unknown reason, I’m not sure if it’s due to it switching over to title based match or not because when I look at the info xml for the movie in my plex library it has the guids:
```
which going by doing searches on trakt for each id links to the correct one which is the one I already had marked in my library and not the one that plex sync beta matched against.
Anyways I’ll re-enable the plex sync again once I’m home in the next hour or two so you can do some testing on my account this week to find out why it just does not work for me, especially when it comes to it never scanning in any tv shows.
Sync hasn’t happened for me since September 1. Read through the last ~50 posts and didn’t see anything that led me to resolution, so posting now. Please note everything was working beautifully until it apparently stopped a week ago – only logged in to Trakt today to check on something and noticed my history for the past week is nonexistent.
I have the correct webhook URL in the Plex server settings. It hasn’t changed.
I can see my server, which shows up as connected and owned with my user selected, in the Plex Sync settings. All of my libraries are shown, and all are marked to sync. It says “Connected to Plex” with a checkmark at the top of the page.
Under Data Syncs, it says, “No data has been synced yet.” That’s clearly not accurate, since I have years of data up to September 1.
I’ve clicked the red Sync button for my server. I’ve clicked Save Settings. I done this multiple times today.
In the Plex Webhook section, it says, “Plex has sent 67,891 events to your Trakt account. The most recent event was Sep 8, 2025 1:47 PM.” It’s clearly connecting.
The Plex server is up to date and has been restarted multiple times in trying to resolve this.
This thread is about the new Plex Sync, but it sounds like you’re asking about the Plex Webhook. These are 2 separate features. I’d recommend opening a direct support ticket and we can provide some things to try regarding the webhook.
I dunno. I’m talking about the thing titled Plex Sync in the center of the menu bar under Settings and linked in step 1 of the first post here, with all of the info I described and the webhook URL near the bottom of the page. If that’s not Plex Sync, my bad but you can probably understand why I ended up here.
Agreed, it is a big confusing since right now it’s in transition while we improve the Plex Sync and also position how the Sync and Webhook will work together.
@Journey-Over I manually ran 2 syncs and they both completed in about 90 seconds. The first added 1,043 episodes to your library from the date 2025-09-07 and onwards. I then ran a second sync from 2025-08-27 and that added 3 additional episodes (and skipped the 1,043 since they already existed).
So, the sync seems to work ok in general when I run it. Checking our logs, I see several 401 errors (which means auth failed) when trying to sync using our automated process. Is your server behind Cloudflare or some other provider that might have security measures in place? I’m still trying to determine why it would be getting auth errors when it’s clearly working when I manually run it.
Nope my server isn’t behind Cloudflare nor any other providers that put security measures in place so I’m not sure what the cause of the 401 errors you are seeing are from, are the 401 errors hitting when connecting to an IP or a website? I’m wondering if the 401 errors are the reason why I haven’t seen any scans other than the 5 I had mentioned about before between the 26th of last month till now (not counting the two you just did this past hour), but either way it does confuse me on why it’s hitting 401 errors to begin with.
If there is anything I can do (short of just adding in more tv shows and movies), do let me know!
also I’m not sure what causes this, but every so often when I go to browse to the plex sync settings I end up seeing this
I’ve since added more stuff to my plex server and so far have had only 1 scan that happened that added a single movie even though I had added a lot more between your two manual scans and the auto scan that happened and this message. I’m guessing it’s still hitting a ton of 401 errors @justin ?
Yes it is getting 401 when trying to initially read the libraries. I’m wondering if it’s actually some rate limiting or some other Plex error, that is being returned as a 401 (which typically means invalid auth). Do you see these 401 errors in your Plex media server debug console? I wonder if there is any more info there.
@justin nope I haven’t seen any 401 errors in the debug console and I’ve left it on the console window for over an hour to catch anything, I also looked/searched through all the Plex Media Server.log files in the Plex Media Server\Logs folder (6 logs in total) and didn’t see a single 401 error in any of the 6 log files either. So I’m honestly at a loss on why it’s hitting 401 errors for my libraries, just to add onto all of this I have no issues with any other programs that I use that are connected to plex/plex libraries.
Thanks for checking. I wonder if it’s actually a Plex hosted service that is producing that error then. That at least gives me another angle to investigate.
It’s not a problem at all! Hopefully you can figure out what the issue is as I would love to get this working so I can actually start using it more. If you need anything else let me know, but at least so far it hasn’t synced anything in; in the past 12 hours (and I’ve added stuff in the past 12 hours to my plex so there is at least some stuff to test against) so hopefully we can get this 401 error thing solved soon enough.
Not sure whether you’ve ever looked at this but it might give you some ideas too to implement in your code for Plex Sync as it does seem to support bi-directional watch list syncing:
