Wanted to update everyone that responded to the resolution.
So after installing the 2 new CA's and new Client certificates in RACF.
I normally use Firefox or Edge as my browsers and neither worked, but never
used Chrome.
I tried Chrome and Poof, got a secured HTTPS connection, That lead me down the
mis-matched path/not found paths.
I looked at Edge and found an old copy of the original certificate zosmfca was
still there in a few places. I deleted all of them and poof my new
certificates was used and https started working.
Firefox, I didn’t find any old certificates, what I found was it didn’t
automatically import my 2 CA certificates. So I had to manually import and
then it then it started to work correctly.
Thanks for everyone's ideas and help.

I am working with out security folks also, they are requiring TLS 1.2 only
connections, there's a local override file you can add to force all connections
to TSL1.2, but be careful, if you use the JES2EDS (email delivery system) you
also need to force TLS 1.2 via a SSH daemon or adding the TLS 1.2 parm in
CEEPRMxx
for z/OS 2.3 and beyond
/global/zosmf/configuration - add
local_override.cfg
IZU_SSL_PROTOCOL=TSL1.2
if you need to force TLS 1.2 via LE
add
ENVAR=("GSK_PROTOCOL_TLSV1_2=ON")
I've tested with only the z/osmf local override file and this caused JES2EDS
connections to fail.
there may be some other options, this is the only option that seemed to satisfy
my security folks and still allow everything to work / connect
