You can just manually change that openocd.cfg to add "debug_level 3"
in the beginning and that should give you full debug log for
comparison.

Please show new debug log with this.

Normally target config doesn't specify reset config, it's part of
whole setup on the board+adapter level. Only
srst_gates_jtag/srst_nogate belongs to the target config, it tells
OpenOCD whether communication under reset works, luckily ST does the
right thing there so it should always be possible to attach to a
target with SRST asserted.
