URL of experiment: https://run.pavlovia.org/cathy-hauspie/rpep-study
Description of the problem: I get the error “403 Forbidden (nginx)” when I try to run my experiment. The console gives the error “failed to load resource: the server responded with a status of 403 ()”.
I already tried removing the old cookies from my browser, but that didn’t help. I think the error has to do with the Pavlovia & JSPsych plugins, but I’m not sure.
Thank you!
Hi Cathy,
i had the same problem with one of my experiment. Turns out that for some reason on some versions of the experiment pavlovia fails to create a proper link for running the experiment. Try simply adding /html at the end of the link.

Worked for me!

Thank you for your reply! When I did this, I got the error “404 not found”. Do you know how I can resolve this?
Hello Cathy
one way the get Pavlovia to generate a “new” link is to set the experiment back to inactive and then to running again.
Best Jens
Hi cathy,
I get the same error, did you find a solution ?
solved it for me, thanks Jens!!
I got this too for a new project - it’s fine for older ones. Is it to do with the nginx server load balancing config settings? Last time I got this it started working the next morning.
Sounds similar to this issue
thanks @wakecarter - that was exactly it 
I have synced a Psychopy3 experiment with pavlovia and I’m meant to be covered by a university license (says this on my profile)
When I try to pilot the experiment I get the following error message:
I have tried some of the suggestions above but with no luck
