IP Blacklist not recognizing IPs

[KarstenW]

Hello,

since last week, we have the issue, that an already blacklisted IP will be blacklisted over and over again.

IP Blacklist:

91.134.178.219 255.255.255.255 Deny 10/09/2037 4:27:54 PM 91.134.178.219
91.134.178.219 255.255.255.255 Deny 07/15/2027 6:24:15 AM 91.134.178.219 PBX: blocked for too many failed authentications
91.134.178.219 255.255.255.255 Deny 07/15/2027 6:56:29 AM 91.134.178.219 PBX: blocked for too many failed authentications

I added it manually, we still get a new block message.
I changed time to 10 years of all automatically blacklisted IPs, we still get a new block message.

How can I fix this?

Kind regards

Hi KarstenW,

This is a known issue on current version 15.5.3849.1 SP1 and we are working to get it completely addressed in a future service pack.

That´s funny, because we are still using version 15.0.62928.5 and it worked fine until last week.
