Oracle 19.6 EM Database Express stays Loading after entering credentials.

Hi

Oracle Linux 7

Oracle 19.6, two node rac conteriner database cdb, with 2 pdbs.

Installed a cluster, enabled em database express in port 5500.

lsnrtl status shows

Listening Endpoints Summary...

  (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(KEY=LISTENER)))

  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=XXXXXXX)(PORT=1521)))

  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=YYYYYYY)(PORT=1521)))

  (DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=<<hostname>>)(PORT=5500))(Security=(my_wallet_directory=/oracle/19c/db/admin/cdb/xdb_wallet))(Presentation=HTTP)(Session=RAW))

I go to the em url. Enter sys or system user + password (I do not write container name)

And this what I get:

In cdb1 alert log I have these:
