Hi @Luca D'Eredità do you use a proxy or a firewall to connect to Centreon UI?

Hi @Laurent, neither (proxy or firewall).
I connect in vpn on the Centreon UI.

@Luca D'Eredità which browser and version do you use?

I use either:

FIREFOX 104.0

CHROME 104.0.5112.102

I tried with both and I can’t reproduce your issue.

You have this error is you change other fields on this form?

Can you put your Centreon Apache configuration from /opt/rh/httpd24/root/etc/httpd/conf.d/10-centreon.conf file?

Hi Laurent, yes it’s a tricky situation. Yes we have the same error on every other fields in this form (and even on other form).

How can i put the Centreon Apache configuration ?

Every time I paste the code this form tell me that:

“Something gone wrong”

Can you put your Centreon Apache configuration from /opt/rh/httpd24/root/etc/httpd/conf.d/10-centreon.conf file?

Hi Laurent,

 as I said before, every time I paste the code this form tell me that:

Something's gone wrong

How can I put the configuration to avoid this issue ?

@Luca D'Eredità when you answer to this topic, you can click on “...” then select “code” and past your configuration

I try that already.

Even with the Language set as Apache I have this issue.

Ok you use standard HTTP configuration from Centreon.

This is the first time we see this error.

How many users are connected to Centreon?

You Centreon platform is only available in private network without WAF?

Hi @Laurent,

There is only one user (admin).

Weird thing but by ssh tunneling of Centreon UI port 80 everything works.

And do you try using private mode with our browser?

Yes

Can you try to download the OVA with Alma8 and check if you have the same issue?

I cannot do this because this is customer infrastructure and we cannot create new servers.

@Luca D'Eredità

Some of our users had similar problems because there was an F5 firewall between the user workstation and the Centreon server.

Can you check with your IT, control F5 logs and add a rule for Centreon?
