Authentication Error - Mikrotik hAP ac lite - New Firmware Flash

Userid and password does not let me log into Setup after a reflash.  I just bought a new Mikrotik hAP ac lite.  Reflashed it with the  newest build .elf file and the .bin file, it opens just fine to the NoCall... page.  I log in to setup just fine with the root and hsmm id and password.  I update channel to -2 and width to 10MHz, distance, my log id to my call AG6ST and a simple password. Hit reboot.  It all looks fine, when I open the

that looks fine also. I closely follow the AREDN instructions on the Mikrotik windows update and the pretty good UTUBE video

I see my call sign in the heading and all as it should. Mesh status works, Refresh works.  When I hit Setup (or WIFI scan), and get to the Username and password boxes, I can not get in.  I'm sure of correctly entering my name and password, but it iust flashes a little and returns to the empty username password boxes.  It won't let me log in to update the settings.  I hit cancel and I get the blank page with Authorization Required message.

The elf and bin I used are:
aredn-960-d8f9320-mikrotik-vmlinux-initramfs.elf  renamed to rb.elf in the pxesrv.exe folder

aredn-960-d8f9320-mikrotik-rb-nor-flash-16M-ac-sysupgrade.bin

Some notes I took during install tries are attached in a word file.

I have reset the routerboard a few times (maybe 4 times so far), reloaded the current .elf and updated using the .bin (28 May 2019).  Same result each time after changing to my call and entering/confirming a new password. Yes - used Correct upper/lower case.  Tried different usernames and passwords also at each install.  It won't let in to continue the setup.  Cancel - I get Authentication Required on a blank page.  I can still get back to the original status page

I have previously loaded the firmware on 2 different Mikrotik LDF5 nodes, with no issues using virtually the same tinypxe program method.
I'm using a Win10 computer tinypxe method,

Any ideas on what I might be doing wrong?

thanks for any help!
