WebUI does not stop to ask for security warning confirmation

[DUCARROZ Birgit]

Hi,

Can anyone tell me what the reason might be that I have to confirm the
security warning for a self-signed certificate up to 6 times in Firefox,
practically every time I navigate back and forth in the various menus in
the WebUI?

The security warning does not come up only once, I have to confirm it up
several times practically each time I navigate to another menu.

I have a second Bareos server, with which this is no problem.

Although this seems to be an Apache problem, I can not understand why
this happens to me only with the one Bareos server, and nowhere else.

I have already tried the following in my local browser:
https://ccm.net/faq/14655-firefox-disable-warning-when-accessing-secured-sites
https://medium.com/volosoft/how-to-disable-firefox-warning-potential-security-risk-ahead-f081fbf81a4f

Both approaches do not work.

The only error messages I see in the apache log are ones like this:
==> error.log <==
[Wed Jul 22 09:13:57.508269 2020] [:error] [pid 41174] [client
1xx.xx.xx.71:50076] console_name: admin, referer:
https://server.bla.ch/bareos-webui/job/details/7


Has anyone ever had such a problem with navigating the WebUI?
How might I fix this annoying message?

Kind regards,
Birgit
