Hi Otree-Community,

I want to use Otree HR to deploy a study to Prolific, however, I get this message and cannot create a session-


Could not connect to your oTree site: OTree4xx('Request to "https://xxxxx.herokuapp.com/api/sessions" failed with status code 405: Method not allowed')

Anyone has experienced this problem? Any tips?

Thanks
Juergen

maybe another important fact. I have upgraded otree to the latest version (pip install -U otree), but still HR says 

Your oTree server is running oTree 5.4.2, which is not supported (need 5.10.0 or newer).


how can I solve this problem? 

Many thanks for your guys help!

when I run the experiment locally, I have the latest verison, when I deploy using the otree hub, i have the following message at the server check "Server Readiness Checks You have oTree 5.4.2. The newest version is 5.10.4." 

Why do I have a different version here and how can I upgrade? 

Would be super thankul for quick help

Check your requirements.txt file, oTree-Hub uses the version that is specified there.
