服务器错误 (500) 在部署 Heroku 的 Django 项目时出现密码重置请求

Question

I have deployed my Django Project on Heroku https://billpayy.herokuapp.com/ . When I try to reset the password, it gives an Error 500 page. The Password Reset functionality works fine locally but gives this error when deployed. Also, couldn't decode much from the Error Logs :

Please help me with this.

Answer 1

Solved. The problem was with DisplayUnclockCaptcha Settings for my Google Account. Enabled that and things worked fine for me. Got the clue by setting DEBUG to True.

3 checks to ensure.

1. Make Sure that the E-Mail Account from which you want to send Password Recovery Emails is given Less Secure App Access here .

2. An Additional step that has something to do with DisplayUnlockCaptcha. Make sure that is enabled here .

3. Open you Gmail account -> Settings -> See All Settings -> Forwarding and POP/IMAP -> Enable IMAP.

The above solution did work for me.
