can't use vmconsole anymore

15 Apr 2021

Thanks for your answer, I checked but I am still stuck :

I confirm that the servlet can be reached, according to your recommended
test (Method Not Allowed.):

[root@vs-inf-prd-ovt-fr-501 ~]# wget
https://localhost:443/ovirt-engine/services/vmconsole-proxy
--no-check-certificate
--2022-06-13 10:30:11--
https://localhost/ovirt-engine/services/vmconsole-proxy
Resolving localhost (localhost)... ::1, 127.0.0.1
Connecting to localhost (localhost)|::1|:443... connected.
The certificate's owner does not match hostname 'localhost'
HTTP request sent, awaiting response... 405 Method Not Allowed
2022-06-13 10:30:11 ERROR 405: Method Not Allowed.

I retried ovirt-vmconsole-list.py with "--debug", and looked at the logs :

[root@vs-inf-prd-ovt-fr-501 ~]#
/usr/libexec/ovirt-vmconsole-proxy-helper/ovirt-vmconsole-list.py --debug
--version "1" keys
[root@vs-inf-prd-ovt-fr-501 ~]#
[root@vs-inf-prd-ovt-fr-501 ~]# grep vmconsole /var/log/messages
Jun 13 10:35:41 vs-inf-prd-ovt-fr-501 journal[3112274]: 2022-06-13
10:35:41,222+0200 ovirt-vmconsole-list: ERROR main:265 Error: HTTP Error
403: Forbidden

To be noted,
We did change the engine's CA certificate at some point by following this
procedure
https://ovirt.org/documentation/administration_guide/index.html#Replacing_the_Manager_CA_Certificate
We also renewed the certificates during a standard engine --setup upgrade
to 4.4.10
