Your description is consistent with a damaged/displaced connector that can no longer seat the cable connector as it is out of position. Try *gently* pulling the connector back towards where it is supposed to be mounted with the thinnest grasping tool you have (e.g. needle tip tweezers). If it reseats with a click, you should be fine, but keep in mind that you now know it’s delicate and can be pushed back in at any time.
Good luck.
