JATOS on institution server can't login via web browser

thornt9 · November 2024

Hello all!

I have installed JATOS on my institutional server, and I can officially access it via web browser. It brings up a login page asking for username and password, as it expected from my experience on a local server. I can type in the boxes, but the buttons for sign in and such seem inactive, and the page is unresponsive. Anyone have any experience with this?

Thanks!

Hi!

To be honest, no, I never experienced this so far? Are there any errors in your browser's console?

Best,

Kristian

Turns out there are several, looks like mostly related to internal server errors serving content. Best I can find it may be a mixed content (HTTP serving over HTTPS protocols?) or maybe the content isn't in the right place on the server. I am not well versed in this stuff, but I jumped in the deep end by trying to host a shinyR app and some OpenSesame content via Jatos through reverse proxies in nginx. Trial by fire for sure.

This is what I see as the login page, and it is clear the content isn't being served correctly.

Your sign in page is definitely not served correctly. What does the browser's console say in errors?

Maybe your proxy config has problems. What are you using, Nginx, Apache? Can you post your config here?

thornt9 · November 2024

I am beginning to suspect it is the nginx config. I will post tomorrow when I am back in the office. Thank you for sticking with me on this!

Obviously a lot is commented out - but it does look a bit different from the base file on the jatos pages...that may be the challenge

kri · November 2024

Hi!

First, I added some formatting to your post and I'd recommend to use formatting in the future to make your code more readable for everyone.

Second, there is a JATOS documentation that includes a page about Nginx: https://www.jatos.org/JATOS-with-Nginx.html. There is also a ton of help for Nginx on the Internet readily available. You seemed to have taken some default Nginx config without changing it much. JATOS will not work this way. When you have some more concrete questions please ask again, but this forum is for JATOS specific questions.

Best,

Kristian

As someone who has been using the extensive resources now for NGINX and JATOS, and juggling the requirements for ShinyR and JATOS, as I mentioned in my first response, I feel I was being quite specific and looking for assistance on a decently specific question. I apologize that you do not feel this way. This forum has been literally my last stop on the way to tearing my hair out.

The NGINX config works for ShinyR and as such, seems functional with additional changes to the URL routing within NGINX/sites-enabled.

I appreciate the help, I'll keep digging at it.

Hi!

I just tried setting up local JATOS on my new MacBook, and got the same sign-in error page while trying to log in. Have you found the solution to this problem or would you mind share any recommendations for how to solve this?

Thank you so much!

kri · July 21

Hi!

Your login page doesn't get delivered properly. Can you please reload the page without cache?

Best,

Kristian

Hi Kristian!

Thank you for your fast response! However, it still doesn't seem to work after clearing cache or trying to open it in a different web browser (I was using Safari, but then also tried with Google Chrome -- both gave me the same sign-in error page).

Could there be any other solutions for this?

Thank you

kri · July 21

I assume you are not using any proxy (like Nginx or Apache) on your local computer, right? If not, could you please provide more information:

Please check JATOS's log files in logs/application.log and logs/loader.log and post any occurring errors or exceptions here.
Open your browser's developer console (DevTools) and post any errors that appear there.

K.

ppitha · July 22

Yes, I'm not using any proxy on my computer. I got these error messages from the application.log file, but the loader.log file seems to be empty as there was nothing when I opened it.

Also, I got these errors from the Safari's JavaScript console when first opening the sign-in page.

I first downloaded the jatos.mac.java bundle but that didn't work so I installed Java from adoptium.net and downloaded jatos.zip instead. I'm not sure if there could be some issues stemming from when I was trying to install Java at the beginning.

Thank you again!

kri · July 22

You might have the wrong Java version installed. JATOS currently needs Java 11. It's this one: https://adoptium.net/de/temurin/releases?version=11&os=any&arch=any. And get the JRE (it's smaller than the JDK).

And about the JATOS bundled with Java that didn't work with you. Did you follow the instructions in the installation documentation?
