we have found out that http://copr.fedoraproject.org was used as default API endpoint if no copr_url was specified for CoprClient initialization. This is now fixed in the latest version of python-copr (python-copr-1.84) and we recommend updating to that version. Also we have decided to revoke user API tokens for which there have been accesses through the http interface recently. You can find the list of the affected users in the attachment and we apologize for this. Please, use https://copr.fedorainfracloud.org/api/ to retrieve new tokens. If you know you have been using CoprClient without specifying copr-frontend URL and you won't find yourself in the attached list, please, go to https://copr.fedorainfracloud.org/api/ and regenerate your tokens as well.
