Database Express Setup: This site can not be reached

Note: These steps are for TEST non-production databases only.

Configuring/enabling EM express on HTTPS should be simple, by running only:

SQL> exec DBMS_XDB_CONFIG.SETHTTPSPORT(5500);

But after configuring it you may still not be able to access the web page and show the error “This site can’t be reached”

The reason for this can be permissions on the wallet files:

[grid@rac1 ~]$ ll /u01/app/oracle/product/19.3.0/dbhome_1/admin/orcl/xdb_wallet
total 8
-rw------- 1 oracle asmadmin 3864 Apr 15 17:40 cwallet.sso
-rw------- 1 oracle asmadmin 3819 Apr 15 17:40 ewallet.p12

The correct permission is 600, but when database is on top of ASM with role separation, then group should also have read permission on these files:

[root@rac1 ~]# chmod 640 /u01/app/oracle/product/19.3.0/dbhome_1/admin/orcl/xdb_wallet/*

After changing it, the web page is displayed.
