[BUG] Can't login into Duplicati any more

[Nordlicht-13]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

After polling the latest image on my linuxserver/duplicati under dockge
I can't login into my duplicati any more.

I get the message:
Connection lost Connection to server was rejected due to invalid authentication. Log in again, or re-open the page from the TrayIcon (if applicable)

I added the two new option to my compose-file:

• SETTINGS_ENCRYPTION_KEY=Secret1612PW
• DUPLICATI__WEBSERVICE_PASSWORD= #optional

And I tried

• DUPLICATI__DISABLE_DB_ENCRYPTION=true

What can be done to login into my duplicati again.

Expected Behavior

Login into WebUI of duplicati

Steps To Reproduce

1. Setup duplicati with YAML-File under dockge
2. Start duplicati under dockge

Environment

- OS: dockge on TrueNAS Scale 24.10.0.2
- How docker service was installed: compose.yaml-file with dockge

CPU architecture

x86-64

Same issue here 😞

[Antonieuk1]

same issue for me unable to login I didn't set any password

[abelfodil]

Same issue for me. Everything works with 2.0.8 tag but stops working with 2.1.0.

[Nordlicht-13]

I entered the password for

• DUPLICATI__WEBSERVICE_PASSWORD= #optional

and now I can login again.
Still get a screen that the connection was lost, but than I can click on login and I get the duplicati login.

Same issue for me

Same issue here

[j0nnymoe]

With everyone that's saying "Same issue here" - it would be helpful to know if you've read through the thread and also the readme to add the password env into your deployment method of choice.

Otherwise your just adding an unhelpful comment.

[abelfodil]

This is what I specifically tried: arch-anes/self-hosted-services@3e9f044. I also tried disabling encryption via DUPLICATI__DISABLE_DB_ENCRYPTION=true (ref).

Either my backup config is wiped or I get a "Failed to get nonce" error at login.

The same issue happens with duplicati/duplicati image so I feel like this should be taken to upstream.

[aptalca]

Did you try adding it as a regular plain text environment variable? The changes you made have several moving parts.

[tugdualenligne]

Yes, I tried adding SETTINGS_ENCRYPTION_KEY but the error persisted.
I then tried adding the DUPLICATI__WEBSERVICE_PASSWORD but error persisted again

[Antonieuk1]

for anyone using unraid you fix the login problem by resetting the docker image and going into the docker log
if you watch it boot you will see a html token copy and paste that into a browser and go to that address and set your own password i did have to delete Localhost and add the IP address of the server at the start of the token and it will solve your problem
