Hey it's me again,

our sessions are running smoothly so far. We had to excuse one participant since they encountered the following problem when trying to open our participant link:

"Invalid hash parameter. use_secure_urls_ is True, so oyu must use the participant-specific URL."


We asked them to try a different web browser and to deactivate any addons if they feel comfortable with that but that all didn't seem to fix it. My guess it's somehow related to the router or a firewall on the router maybe? But this seems to be a rare issue.


Best

Michel

We had this problem occuring regularly around 5-8 times at a total of ~120 participants. We figured out that usually copying and pasting the link into a new tab or browser solved the issues, with exception of the first time it occured. However, we didn't see the screen or what participants were doing exactly, so who knows what happened. 

The participants always got the link from us via zoom. I guess the issue is related to this. So whoever encounters something similar, just let them repeatedly open the link in new tabs, new browser or new windows :)
