Thanks for the reply Didi.

I have checked the logs, but it does not seem to show anything when I try and access the WebUI. I run tail -f engine.log and tail -f server.log, but it remains still. This is the same case with the httpd logs.

I checked the status of the engine from my node, and it displays the below:

[root@jb2-client-node01 ~]# hosted-engine --vm-status

!! Cluster is in GLOBAL MAINTENANCE mode !!

--== Host jb2-client-node01.kvm.voxvm.co.za (id: 1) status ==--

conf_on_shared_storage             : True

Status up-to-date                  : True

Hostname                           : jb2-client-node01.kvm.voxvm.co.za

Host ID                            : 1

Engine status                      : {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "Up"}

Score                              : 3400

stopped                            : False

Local maintenance                  : False

crc32                              : 75d3e273

local_conf_timestamp               : 3547513

Host timestamp                     : 3547513

Extra metadata (valid at timestamp):

        metadata_parse_version=1

        metadata_feature_version=1

        timestamp=3547513 (Tue May 12 09:43:29 2020)

        host-id=1

        score=3400

        vm_conf_refresh_time=3547513 (Tue May 12 09:43:29 2020)

        conf_on_shared_storage=True

        maintenance=False

        state=GlobalMaintenance

        stopped=False

Everything network related seems to run fine, I can connect to the engine via ssh etc. as well.

I initially just wanted to remove the websocket proxy, and as advised by an article, this can be done by running engine-cleanup. Obviously this was not the case, and it removed everything.

Not necessarily everything, but even if you ask to remove only
something specific, it does more than that. We recently decided this
is too risky and removed that question:

1. When attaching complete logs (thanks for that!), please state the
exact time you tried
to do something that failed (access the web ui, in this case). Your
attached logs have
several different ERRORs, which might be due to unrelated things, and
it's hard to tell
where to look first. Once found, going backwards to try to find the
root cause is usually
easier.

2. Please check/share also httpd logs, and also /etc/httpd/conf.d -
you can compare it
with a fresh engine you can setup on some test vm somewhere, it should
be mostly the
same.

3. Also please check/share engine-setup logs, at
/var/log/ovirt-engine/setup. You can search
there for httpd or apache.

4. I have a feeling, just a guess, that you are missing
/etc/httpd/conf.d/z-ovirt-engine-proxy.conf .
Not sure what might have caused that. setup after cleanup should have
created it.

Best regards,
