This is the last log that I see:

And this may be the processes :
(Not sure, probaly need to reboot & clean ?)

Beside that, reverting the last 2 commits on 5551 doesn't seem to help:
 Revert "t5551: make the test for extra HTTP headers more robust"
 Revert "submodule: ensure that -c http.extraheader is heeded"
