I am unable to log in to the web GUI. I know the username and password but when I enter them, nothing happens.

I'm running ESXi 8.0.3.
Server - Dell PowerEdge R660, Intel Xeon Gold 5418N (2 sockets, 24 Cores), 256GB RAM, 12.22TB HD with 12.21 TB free)(

We purchased EVE-NG Pro on 4/23/2025.

When I run dbkg -l eve-ng I get the following:

root@neteve:/# dpkg -l eve-ng
Desired=Unknown/Install/Remove/Purge/Hold

I checked the permissions on /opt/unetlab/wrappers/unl_wrapper and noticed it was not executable. So I changed the permissions via chmod +X can now run a "fixpermissions" but now get the following:

root@neteve:/# /opt/unetlab/wrappers/unl_wrapper -a fixpermissions
PHP Warning: file_get_contents(https://127.0.0.1:445/challenge): Failed to open stream: Connection refused in /opt/unetlab/html/includes/functions.php on line 60

PHP Fatal error: Decoding error - Unable to call protected function keygen in /opt/unetlab/html/includes/functions.php in Unknown on line 0

When I try to restore the db with "/opt/unetlab/wrappers/unl_wrapper -a restoredb" I get the following:

root@neteve:~# /opt/unetlab/wrappers/unl_wrapper -a restoredb
PHP Warning: file_get_contents(https://127.0.0.1:445/challenge): Failed to open stream: Connection refused in /opt/unetlab/html/includes/functions.php on line 60

I tried restarting mysql with "systemctl restart mysql" and still get the same error as above.

Assistance is much appreciated.

Just did an apt update, apt upgrade, reboot. Still not able to log in to the GUI.

first of all enable virtualization. then run these commands in order
unl_wrapper -a backupdb
unl_wrapper -a restoredb
reboot

Hyperthreading is enabled on the vmware host. We've been running labs on this EVE instance for a couple months and this just started happening last week.

***kvm-ok command***
root@neteve:/opt/unetlab# kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
^^^ Does this confirm virtualization is enabled?

I tried doing the backup command and this was the result.

root@neteve:/opt/unetlab# unl_wrapper -a backupdb
