Describe your issue

The topic is about DAGU admin configuration. The screen just after Dagu installation. I put the admin name , password and confirm password. When I click on the button “create account”, this message appear : “host “dagu.monsite.xyz” is not allowed; add it to allowed_hosts or set public_url”. Thanks for your help.

Share relevant logs or error messages

@arnohgf
Try this

sudo nano /var/www/dagu/.env
# add this line :
DAGU_PUBLIC_URL=https://your-dagu-domain.tld
sudo systemctl restart dagu

You can also try upgrading from the testing branch

yunohost app upgrade dagu -u https://github.com/YunoHost-Apps/dagu_ynh/tree/testing

Thanks ! I can register and move to the next step… but on the next step (login screen), i am in a loop. , I put username/password and I come back to the same screen with empty fields.

6

Do you mean when accessing /login ? That’s weird because, normally, after registering, you should be logged in…

Did you clear cookies or try in a private tab ?

7

Yes, I move directly on login screen after registered the user.

I am in a loop. I fill in the blank fields in login screen , click on button “sign-in” and the login screen come back, and so on, and so on , …

I try clear cookies and all history informations without effect. I try private tab, other brother, other pc without effect.

8

Can you share the dagu service log and the errors displayed in the browser console?

9

there are no errors displayed on the login screen

10

:person_shrugging: I would try reinstalling from scratch…

yunohost app install https://github.com/YunoHost-Apps/dagu_ynh/tree/testing
11

I got /api forbidden in the browser console

I have successfully logged in using this branch GitHub - YunoHost-Apps/dagu_ynh at api · GitHub
I have launched ci test

12

no change with testing version.

But In nginx access log, I see some 401 errors :

Really strange.
I have installed dagu from testing with no issue on both bookworm and trixie, local & fqdn domain.
I can log in, use api, create workflow, change password.
What other features have you tested to get this error and what am I missing ?

14

Some features require a paid license.

15

I 've just tried to login. Cleared cookies, opened login page > login loop to login page with console errors

16

Which version are you using : from the api branch you created, yesterday’s testing branch o today’s testing/master ?
The thing is that there seems to be a temporary issue with GH at the moment and I’m unable to install any app.
All I can say is that I ran all my tests on servers using either public ipv6 or local ipv4. When I installed dagu on a server with a public ipv4, I ran into the same 401 errors. But I removed the app and can no longer test :man_shrugging:

17

Installed v2.26 on a server with a public ipv4 (without permissions specs on /api) and now dagu works as expected (no longer errors 401)…:person_shrugging:

Yesterday, I deleted Dagu on Yunohost admin panel and after I installed it with the command line suggested :

“yunohost app install https:// GitHub - YunoHost-Apps/dagu_ynh at testing · GitHub”
