My iPad stop recognizing my lighting to SD adapter

Yesterday my iPad was uploading my photos with no issues, I even store them on an external drive “easy store” that I plug in after downloading the photos. Well on the same day just a few hours later after another photo session I put my lighting to SD adapter into my iPad to upload more photos to adobe’s lightroom and it was saying No connected devices? So I went into my files to see if I could download the photos that way then import to Lightroom but it still was not popping up where it usually does in the file area? So I took it out thinking maybe something was wrong with my lighting to SD adapter, and I stuck in my lighting to USB adapter with my easy store attached like always. And I’m files where it usually pops up easystore it did not, just like the memory card reader? Why would my IPad just stop recognizing these devices only a few hours in between the last download? I thought maybe the area on the IPad where they plug into was going bad? So I stuck the charger in to see what the deal was and it charged right up no problem? That’s odd right??? So I went and got another lighting to sd card reader and was praying the new one would work. Nope! No go! So what happened? Did something get bumped or was it being played with by on of my clients kids and they accidentally turned something off? Is there a way to fix this issue, I don’t understand why it won’t read anything I stick in it but it charges?
