No login possible after update

[Axel Becker]

Hi everyone. I updated HexOS on 3rd march 2026 and now I can´t log into it. "Server not availabe" is the message. The server runs fine and I have access to all my files, but I don´t want it running all the time. I use it only as data storage. What can I do?

 

Cheers

Axel

Try the following. Most likely this will fix your issue. If this does, TrueNAS has a fix that is in it's next update.

 

1. Login to TrueNAS interface.

2. Left side select "system".

3. Then after screen refreshes select "shell" from the list.

4. Paste in the following command. *Can't use normal short cuts* Will need to use Shift + Insert Key for pasting.

sudo python /usr/lib/python3/dist-packages/middlewared/scripts/vendor_service.py

 

If that works within about 1 min you should be able to go to deck.hexos.com and see your server or claim it.

You might need to run this after reboots. 

 

Let us know if this works.

 

Thank you,

Hey I just tried this because hexos is reporting my server being offiline but I am still able to use all the apps. I pasted the script and I got an error "Failed to start transient service unit: Unit websocat.service was already loaded or has a fragment file." I gave it a minute and hexos is still reporting offline, any other ideas?

If you're seeing 'Failed to start transient service unit: Unit websocat.service was already loaded or has a fragment file', then you can try:

sudo systemctl restart websocat
