Failed to load Nagios XI

[xdatanet]

After 2024R2 update I can see the sso option.

In the page a message on top informs me the I have problems with HTTPS... (???)

WARNING:
HTTPS must be enabled to use Azure AD SSO. Using SSO without HTTPS is a significant security risk and may expose your credentials. Configuring SSL/TLS in Nagios XI 2024

Update: this warning is by design... (sorry, I did not understand)

I can see the page for seconds and then a subpage informs me about another error.

Failed to load Nagios XI.
An unexpected error occurred. Please try to reload the page or switch to our Modern theme. If the issue persists, please reach out to Nagios Support.

Please, give me a feedback...

In the last 2024 version (I revert to prevoius version), changing to Neptune, at the first update of the interface Nagios gives me the same error.

I found in log the error:

"GET /nagiosxi/includes/lang/json/en.json HTTP/1.1" 404 196

Browsing the folder in Nagios Server I cannot found any en.json but only en-US.json.
Copying the file in en.json resolve the issue.

Now I'll try to re-upgrade to R2 in order to discover if the modern theme error in the SSO page is similar.

Ok, the problem was definitly that the SSO page made with neptune theme also if I have modern dark.

Now the error is gone.
