Cannot login after ios app re-install

Trying to solve a problem with HA Cloud, I uninstalled the Homeassistant App on my iPhone.
The HA Cloud & remove issue is now resolved.

The reinstall iOS App askes me to authenticate (username / password).
Then the 2FA token, after which the following error is displayed.

The HA Logs give the following exception…

The log files from the app, show data for the sensors being passed to HA, getting respones, then…

The same App works on my iPad, without issue.

HA works from a web browser on the phone.

Any suggestions?
