Topic: Firewall suddenly started blocking a well used IP address

[misnerspace]

I have posted this on the bug tracker just in case it is a bug. My gut feeling is that it isn't, but I may be wrong!

The SME firewall has started denying IPs from a specific cloud service that we started using about 5 weeks ago. I am trying to find out whether this is a bug with SME server. I am curious to know why the firewall would suddenly single out a specific IP address and start blocking it. I haven't updated or installed anything new. Unfortunately this site serves as our Student Information System so we need to get access to it. I need to identify whether the problem is with them or with our server.

I have attached a log file which contains all instances of the problem. It seemed to have started about 2 weeks ago (there were only two issues) but then somehow it magically resolved itself until today.

NB:Thanks for all your hard work on making a quality piece of software, my school really appreciates it.

It's very strange as it has been working fine until today.

Thanks!

The problem website is PowerSchool. We are having no other problems with any other website.

I had a look through previous threads and noticed the following

There quite old posts but I think they could be relevant.

I am not too sure on how to proceed on this, so any advice would be most appreciated.
