Continuing the discussion from Can't add new directories to existing libraries – "Your changes could not be saved." : Server Version#: Player Version#:

I’d recommend you to not re-enable IPv6 support, unless you know for certain that both your router and your ISP do fully support IPv6.

Another Follow-Up: You remember I mentioned that I have three Windows PMS and one of the other Windows PMS started out like it was going to have the same problem but it corrected itself after I rebooted and saved my library changes on the local PC using 127.0.01? That PMS had IPv6 enabled also but…

I fought the IPv6 battle with my ISP ten years ago. It just so happens that IPv6 is my primary responsibility. I have to get the Environmental Protection Agency (EPA) internal network IPv6-Only (without IPv4) functional in three years. So my network does fully support IPv6 [image] Test y…

The hardest part of my job is to convince System Administrators and System Owners to Enable IPv6 when everyone else is recommending that they should Disable IPv6. Therefore, I have to be willing to take the risk of using IPv6 myself before I can be confidence in asking others to do so. [Enable IP…

It’s probably no surprise that after I updated my PMS today, the problem returned. I searched Reddit and saw many people with the same problem but there doesn’t appear to be a single solution that solves everyone’s problem. I tried turning IPv6 off, rebooting my router, rebooting my PC and nothing…

[image] Problem Adding a Library NAS & Devices @ChuckPa I noticed the same thing when our automated PlexAPI tests broke today with PMS 1.31.0.6654-02189b09f. Specifically, the POST /library/sections API command is returning a status code 400 Bad Request. When trying to…

Got this today, on a 100% new installation, I can’t add any library. I tried the “Disable ipv6” thing, restarted the server, still no-go. Getting “Your changes could not be saved.” in the web page. Getting the following error in the Network tab: 'agent' is missing or invalid 'language' is invalid…

Please enable server debug logging, stop and restart server, enable debug loggin in the web app as well, reproduce the issue, then fetch logs from both server and web app, please. (please zip logs before sending) https://support.plex.tv/articles/201611836-plex-web-app-logs/

Installing an Older version of the PMS and then reinstalling the Latest PMS resolved my problem this time but I’m certain that it won’t be long before I will see it again. Perhaps when the PMS is updated again. So far, I’ve only seen the problem on Windows 10. I have not seen it happen on my Linu…

Just wanted to say I have exactly the same issue. I’ve tried everything suggested in this post and this other post also: [image] "Your Changes Could Not Be Saved" error when I try to add a media folder on new install Desktops & Laptops Thanks! “Have you tried turning it o…
