Same issue can be reproduced on UC22 as well

Failure rate: 100%

Dumb question could this be because we try right after detecting the re-plugging connectivity? I think a few retries with some exponential backoff can't be bad in this situation while we just detect connected && check connection, which is not optimal. What do you think? Can you just run this command and see if running the second one a few seconds from the first fixes this?
