    The scan output looks ok with respect to signal level and advertised encryption protocol. It's not clear to me why you're not staying connected with this specific AP. A driver regression perhaps? Or perhaps an issue with wpa_supplicant? Although you did mention that successfully connects to your mobile phone hotspot. For completeness, can you also share your wifi hardware details please?

    I see many bugs associated with this and other related hardware using this driver. It could be a regression associated with firmware perhaps.
    Code:
    Model: "Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter"
      Vendor: pci 0x168c "Qualcomm Atheros"
      Device: pci 0x003e "QCA6174 802.11ac Wireless Network Adapter"
      SubVendor: pci 0x1028 "Dell"
      SubDevice: pci 0x0310 
      Revision: 0x32
      Driver: "ath10k_pci"
      Driver Modules: "ath10k_pci"
    At this stage a bug report might be in order.
