XF 2.2 ERR_TOO_MANY_REDIRECTS

[nanto]

Hello

Since yesterday evening the homepage of my forum is no longer accessible.
The subpages are accessible.
xenForo version is 2.2.13

The message appears in the browser:

ERR_TOO_MANY_REDIRECTS

This affects all browsers and operating systems and is not due to the cookies.

Nothing has been changed anywhere.
I made the last updates about two weeks ago.
Settings in the admin control panel, such as the board URL, have not changed for years.
Likewise the entries in .htaccess.

When checking with Chrome Developer Tools, the loop also appears.
Additionally, service_worker.js line 78 is referenced.



A file integrity check in the admin control panel was ok.
(Well, at least until I commented out the line 78 times to test it.
not anymore…)

Now I'm running out of ideas as to what it could be.
The sudden appearance itself is inexplicable to me...

Here is the content of the .htaccess:

#Header set Strict-Transport-Security "max-age=63072000; includeSubdomains; preload"

The original .htaccess file didn't work.

An entry in config.php for
Turning off all addons didn't work either.

$config['enableListeners'] = false;

The response headers of your server shows you are using nginx so there is no use of .htaccess .. check your nginx configuration
