We kind of dislike top-posting on the list. No biggie, but try to
refrain from top-posting if you can.

As to your problem, the first thing is to add "debug true" to
/etc/gssproxy/99-nfs-client.conf first, then have a look at the journal
again. You can also dial up the verbosity by setting "debug_level 3"
in the same file.

I don't think that the AVC denial is the cause of the problem. It looks
like the denial is caused by gssproxy trying to let you know it failed.

Gmail always puts replies on top. I forgot about that.

I see nothing in the journal. With debug_level 3 should I see something?

99-nfs-client.conf:
[service/nfs-client]
  mechs = krb5
  cred_store = keytab:/etc/krb5.keytab
  cred_store = ccache:FILE:/var/lib/gssproxy/clients/krb5cc_%U
  cred_store = client_keytab:/var/lib/gssproxy/clients/%U.keytab
  cred_usage = initiate
  allow_any_uid = yes
  trusted = yes
  euid = 0
  debug true
  debug_level 3
