Hello, 
I recently updated my LimeSurvey version and operating system. But since then, I can access directly to the admin page without authentication. And when I try to logout and login again, I get the "Gateway Timeout The gateway did not receive a timely response from the upstream server or application." error. I looked through the forum and web, but unfortunatelly I couldn't find why that might happen. I want to redirect to authentication when the url is called. Can you help me?

Thank you,

How did you update? Manually or via Comfort update?

If manually (e.g. via FTP), make sure all files have been uploaded correctly. LS has a lot of files and in my experience it is not too uncommon that some files do not make it to the server via FTP. So this is a possibility.

As you also updated the operating system, have a look at your PHP version and if it is supported by Limesurvey LS6.

Hi,
I've updated manually. And my php version is according to the requirements of LimeSurvey 6. But I couldn't quite understand why FTP might affect that. Because I downloaded the zip file for LS and moved it into the required location, I didn't touch the files specifically.

> But since then, I can access directly to the admin page without authentication.

I think you use a specific Authentication system. Can you check on plugin list the Authentication plugin activated ?
 

Actually no, I'm not using a specific authentication system. But how can I check the plugin list?

If you didn't upload the files via FTP obviously FTP won't be the issue. I was just mentioning it as a possible cause of your issues. As we had basically no information on how you updated, I just tried to start somewhere and ask questions and throw this possibility out there.

And my php version is according to the requirements of LimeSurvey 6.

OK, so it is within the specifications. For reproduction and trouble shooting purposes it could still be important to know your exact PHP version...

If you don't have to authenticate, i really think you have an authentication plugin …

Hi,
I'm using PHP version 8.2.13.

Hi,
There are 3 plugins available in my settings: Authdb, AuthLDAP and Authwebserver. Authdb is active and the other two is passive in my situation. Which one do I need to activate or change its status to passive in order for my site to run properly? Because yes I can make it direct to authentication somehow, but I can't login. That's the main problem, it gives 504 Gateway Timeout error.

You need only AuthDB activated

> Because yes I can make it direct to authentication somehow, but I can't login.

I don't understand this sentence.

Else : do you have access to PHP error log ? Maybe something with session save_path ?

The problem is, I can access login/authentication page, but I can't perform login action. When I write all my info and click login, it throws 504 Gateway Timeout error. And no I can't access PHP error log...

Can not help, since it's related to your hosting service.

Ok, now it is clearer what the actual problem is, because I (and I think Denis as well) read your problem as:

"I can access the platform without having to login."

Actually, your problem is "just" that you can't login, correct? You se the login mask, you can put your login data and when you submit, you get a 504 Gateway timeout.

What confuses me is that you say it is on your own server, but you can't get access to the PHP logs? Because this seems to be a server issue to me.

You need to speak to the person responsible for your Limesurvey installation in your organization.

Hi,
We've checked our php logs and there isn't any new logs related to login issue.
