Users cannot login after password reset or using a different browser than for the registration

[arpad]

I set up a Taiga server using Cloudron and the default settings: https://taiga.reliabilityworkshop2020.com/discover.

I invited my collaborators, they could sign up and use it but when one of them forgot his password and asked for a password reset, he could not log in anymore.

• As an admin, I manually changed his password but he (we) could still not log in.
• Then I tried to log in to my account using a different browser and even the same browser in incognito mode but I could not log in anymore. Note that I was (as I still am) logged in to the Taiga instance in the browser which I used for my first log in (Edge), and I can still use it from there.
• The emailing seems to be properly configured because we receive emails from the Taiga server.
• Automatic updates are enabled, Taiga version: Taiga 6.0.9.
• I restarted Taiga a few times and also increased the resources it can use but they did not help.
• There is the following warning in my Cloudron account

reliabilityworkshop2020.com

PTR DNS record (PTR) did not match.

Hostname: 20.93.160.11

Expected: my.reliabilityworkshop2020.com

Actual: null

Email Status is checked every 30 minutes. See the troubleshooting docs for more information.

But I do not know how to resolve this or if this could be an issue.

Do you have any idea what could be the problem and suggestion to resolve it?

Have you configured Taiga to use the Cloudron usermanagement? If so can you check if they can maybe just login using either Cloudron credentials?

@nebulon Thanks for the suggestion. I haven't configured Taiga through the Cloudron user management. I invited the users through Taiga, from a specific project.

@arpad hm at least the PTR mismatch has nothing to do with this issue. To be specific, if you have installed Taiga with default settings, then it is configured for LDAP use, which means it also uses the Cloudron user-management. If you have invited people, who also have an account on your Cloudron (same username/email) then they might clash. If this is not the case, we have to look for something else, maybe the app logs reveal something during login?

Ok, thanks; I did not know that.

I contacted the user to verify this and will get back to you once I have his response (also with the logs as well if needed).

Related to a part of my original issue report:

Then I tried to log in to my account using a different browser and even the same browser in incognito mode but I could not log in anymore. Note that I was (as I still am) logged in to the Taiga instance in the browser which I used for my first log in (Edge), and I can still use it from there.

This is not an issue anymore with my account. I'm not sure what happened but I can log in now from any browser.

@nebulon The user with the login issue does not have a Cloudron account.

From the admin panel I deleted the problematic user account and invited the user again (with the same email address as before).

So far everything seems to be working, although I do not know what might have solved the issue. In any case, thank you for you help.
