Edit: migrating env back to python2, still not possible to access site by domain name, accessing using ip rise an error:

Fixed! Also if you’ve got pickling issues, I’d suggest you a bench clear-cache Or maybe a FLUSHALL would work within redis-cli too. Does pretty much the same.

Brave enough, remove dump.rdb

@achillesrasquinha I had to restart the server. redid-cli FLUSHALL did not work for me. But thanks it gave me the idea
