Unable to add Telldus Live integration with Home Assistant 2023.4.3

The problem

After upgrading to Home Assistant 2023.4.3 I lost my Telldus temperature sensors from Telldus Live integration. I quickly checked the status from https://live.telldus.com and sensors were correct there. I deciced to delete Telldus Live integration and add it again. I removed the integration and now when I try to add it, I get error "Unknown error generating an authorise URL."

Full error from the logfile is:
ERROR (SyncWorker_0) [tellduslive] Failed to retrieve authorization URL: Token request failed with code 404, response was ''.

Looks like it was a problem with Telldus side. I tried to add integration again and now it worked.
