+1 on upgrading your OpenOCD to a 2020 version. Could be you're using v3 silicon here, that changed some things in the JTAG logic.
Other Forums have reported errors trying to run JTAG with the WROOM that are fixed by getting the
more current version. Unless someone has made a tool change, it is a pain since after removing the installed version and installing the more current release from https://github.com/espressif/openocd-esp32/releases
You will probably have to edit tools.json to reflect the name and hash of the updated version.
I am quite sure I was getting connect failures prior to updating my system. You will want the esp32 specific load of the tool for sure.
