Nextcloud, unraid reconnect docker to share

I have nextcloud setup on my unraid server with marisdb. I love it and everything has been perfect till last week I opened the webpage and It was giving a PHP error. From what I have learned, when you get an update notice in unraid you are not actually updating nextcloud but more like fixing issues with the outdated container.

So I found a few posts, probably with some bad information saying to update nextcloud in the container cmd. Well that got stuck during the update process. I then deleted the container and installed the latest version but that showed up like it was stuck updating also.I then deleted the user data folder for nextcloud and reinstalled again.
Now nextcloud works but I cannot figure out how to get the new install to connect to my previous share. All my files are still there and but every time I try to link to it Nextcloud gives me an error.
