I’ve checked the documentation, and unless I’m missing something, there doesn’t seem to be a way to remove a blacklisted IP from Fail2Ban via the API. It would be great if this functionality could be added, as it would be much cleaner to handle this through the API instead of relying on less elegant web request workarounds.
Thanks for all the work you put into KeyHelp it’s a great panel, and these additions would make it even better.
