Connection Error on Heroku

[Nanyin Yang]

Hi! I am using Heroku, and I met with the following error:

Error 1 connecting to ec2-3-226-159-214.compute-1.amazonaws.com:13299. [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:1091).

Here is a screenshot:

This is a two-player game, and the role is randomly assigned after all players arrive. It runs smoothly on my own laptop under the production server mode. But on Heroku, when all players arrive, the last player will have the above error on the screen. And if I refreshed the page, then the error message disappeared, and the whole game can begin to run. And when finishing one app and moving to the next app, this same error appeared again. And after refreshing the page, it disappeared.

Any suggestions will be much appreciated!

Best,

Nanyin

This is a Redis error. Either downgrade Redis or upgrade oTree to 3.x or 5.x.
