OS: Win11
PsychoPy version: 2026.2.3
Standard Standalone Installation? y
URL of experiment: Pavlovia
Do you want it to also run locally? no
What are you trying to achieve?: sync project with Pavlovia
What did you try to make it work?: It had been working fine. I have successfully synced this project several times. This time, I got an invalid_grant internal error. In some googling, it seemed like an SSH key would help. I went through the process of making one of those and added it to my Pavlovia gitlab. I closed PsychoPy and re-opened, but the issue is continuing. I tried to log into Pavlovia in PsychoPy, but the same error shows up for that. I saw someone suggest trying it from a hotspot instead of through the university wifi. The same error message appears when I try connected via hotspot.
