Hey there @kane610, mind taking a look at this issue as its been labeled with an integration (unifi) you are listed as a codeowner for? Thanks! _{^{(message by CodeOwnersMention)}}

Kane610 commented 3 years ago

I've never seen that error before. How is your controller setup? Have you tried running it with a previous release of home assistant?

nicolaiort commented 3 years ago

Hi maybe I can help add more information, I just got the same error.

Unifi Controller

Hardware: CloudKey Gen2 Plus
Firmware: 2.1.7
Network Controller Version: 6.1.71 (Stable)
User: A seperate automation user - I tried it with view-only and admin access

Home-assistant

Version: 2021.6.4
Tried older version: Not yet - haven't had time
Integration Config
- Host:
- User:
- Password:
- Port: 443
- Verify SSL: Tried both, setting it to true clears user/password after clicking on submit - false doesn't
Other: I also tried out the community unifi protect integration - it works just fine (same controller, user)

Happy to provide more information, just tell me what you need and I'll do my best :)

gabosom commented 3 years ago

Sorry for the delay. Here's my info:

Unifi Controller

Hardware: Cloudkey Gen2
Firmware: v1.1.13
Network controller: 5.13.32-13646-1
User: separate user (although I also tried with my own account)

Home Assistant

Home Assistant and Cloudkey are on the same network.

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

hey @nicolaiort and @Kane610 - I got this working today by doing the following:

Updated the controller to the latest version
Created a brand new local user in the controller (the new controller UI didn't work, I had to go back to classic for that)
Used port 8443 instead of 443.

Good luck!

@gabosom Thank you for the tip - I use the controller on my CloudKey Gen2 with UnifiOS and this method of deployment doesn't allow creation of users in the controller UI - only in the CloudKey management UI afaik (could be me not looking in the right place).

Are you running the contoller on a CloudKey G2/Dream Machine or standalone?

gabosom commented 3 years ago

I use a cloudkey. Just create an admin with read only access 😉

nicolaiort commented 3 years ago

Well I don't know what the heck I did different this time but it works. Created the UnifiOS User, gave access to my site (same user and permissions as last time) , and added the integration on port 443 (8443 is only for non g2/UnifiOS controllers).

Thank you @gabosom for encouraging me to try it again :)
