Ah wait, the error page comes from Apache. How did you configure Apache to forward all traffic to JATOS?
-
Hi Marko, Everything you did looks fine to me. Are you sure about the URL? And are there any errors on jatos/logs/application.log? Best, Kristian
-
Hi Jana, I doubt that this issue is a JATOS one. Your error msg "Application Error: TypeError: cannot use 'in' operator to search ..." puts it more in the JavaScript/browser side and there, since it only happens with OpenSesame components,…
-
Hi Marko, Hmm, without sudo, just with "./loader.sh start" I get this error ... It's because you started JATOS once as root. JATOS created some files that now belongs to the root user. Either you 'chown' them back to your normal user or yo…
-
Hi Marko, First, you don't need 'sudo' to start JATOS. It will just lead to weird file ownership problems. Then about JATOS not showing anything in the browser: What does the application.log in the logs folder say? Any errors or exceptions? Best, Kr…

This bug is fixed in version v3.8.2 that is about to come out today :)
-
Hi, Those error messages mean that the WebSocket for the batch channel could not be opened. JATOS uses WebSockets for some fast data exchange between the server and the browsers. Somehow those could not be established. But since there are no other …
-
Hi GUO, The changes between the former version on Mindprobe, 3.7.4, and the current version 3.8.1 are mostly around the JATOS API. The JATOS API is mostly about study export/import, result fetching, and administration - it is not about study runs an…

Hi GUO, It happened for two times that one participant (Worker ID: 291371) has finished tasks but there was no entry record on Jatos. We had tried to check on Jatos when the paticipant was doing the task, but Study Result State has no message of &qu…
-
Thanks so far! Could you please send me the whole content of cookie JATOS_IDS_0? Best, K.
-
The data is about 1800-1900 KB~ That might be the reason if you sent the data often. Sending data often can overload the network and when you participants network connection is weak it can lead to exactly this behavior ("transfering data" …
-
Hi Moritz, I have seen this before. It's probably a bug somewhere in JATOS' cookie handling. But the problem for me is that I cannot reproduce it on my JATOSes. It seems to happen only with certain browsers. I try to pinpoint it in the source code t…
-
Hi GUO, Difficult to say. But since some of your study runs do finish after a long "transfering data" my guess is that our data is either to large, or you sending data to often, or a combination of both. How big is your data and how often…
-
That is my first guess, yes. K.
-
Hi Joshua, Does this happen on a local JATOS too or only with a remote one like Mindprobe. My hunch is that it has to do with OSWeb/OpenSesame and not so much with JATOS, @lvanderlinden what do you think? Best, Kristian
-
Hi IIaria, Do you use 3.8.1? I ask because we fixed an issue with the loader.bat in this release. I'm just trying to figure out what caused your problem. Best, Kristian
-
Hi, I'm not sure which possibilities OpenSesame offers but with JATOS you could just add another component that is doing your questionnaire and put it in front of the OpenSesame component. Of course, since it's pure JATOS, you would have to write yo…
-
@CuiC, @egarcia Did you get my direct answers?
-
Hi Elena, No problem, I can create accounts on Mindprobe too. Usually I don't but I guess Lotje took a couple days off or something. But I have no access to the info@ email account. So, can you send me your email address (easiest is in a direct mess…
-
Okay, I can confirm, it was just removing the hyphen and then it worked again. I updated the docs: https://www.jatos.org/JATOS-on-DigitalOcean.html. And since you just used it, can you please have a look at the page and check that it is correct, es…
-
I see. Hm. Maybe it has to do with what I found in their docs (https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-compose-on-ubuntu-22-04): Note: Starting with Docker Compose v2, Docker has migrated towards using the comp…
-
Hi Riss, Nice you got it running! I think if you choose the right image in the beginning, extra installing Docker is not necessary. DigitalOcean has those 'Docker x on Ubuntu y' images right to be used. https://forum.cogsci.nl/uploads/345/I4QKV95TRA…
-
You have no Docker container running. There should be traffic and JATOS running as containers. Let's see what happens when you run the JATOS' docker-compose script: docker-compose -f /root/docker-compose.yaml up -d K.
-
Hi Riss, Your JATOS docker is running and port 9000 is exposed? What is the output of docker ps in the terminal? And ufw? What is the output of sudo ufw status verbose? Best, Kristian
-
Hi Riss, To open the ports for HTTP and HTTPS it should the following commands for ufw: sudo ufw allow http and sudo ufw allow https but if you still use JATOS default port 9000: sudo ufw allow 9000 Here is a tutorial for ufw: https://www.digital…

Hi Vanessa, We solved this problem via email. But I want to answer here in the forum to have it documented and it might others. Sorry for taking so long but I had to be sure and check and test it thoroughly. It's a bug in how JATOS checks for the ma…
-
Hi Riss, Not sure what's going on with your server. But for a start it seems like your HTTP(S) ports aren't open: kristian@opossum:~/Downloads$ telnet 159.203.15.124 80 Trying 159.203.15.124... ^C kristian@opossum:~/Downloads$ telnet 159.203.15.124 …
-
Hi! I'm pretty sure it's more of an jsPsych issue. JATOS doesn't care for the data format as long as it's some kind of text (so CSV, JSON, XML - all are fine). Maybe it's some kind of caching issue? Maybe locally your browser's cache is disabled, bu…
-
Hi Jason, You can pass CSS information in the style parameter to the jatos.addAbortButton function. Have a look at the docs: https://www.jatos.org/jatos.js-Reference.html#jatosaddabortbutton. I didn't try it but putting the button in the top shoul…

Version 3.8.1 with the API should come in a couple days :)
