It seems I can't access my cctv through the mobile network anymore. Have o2 blocked this? I need to be able to see my cameras, who do I complain too?

@Bryan_james If you message O2 on Facebook (https://o2uk.co/O2CFB) , Twitter (https://o2uk.co/O2CTW) or Instagram (https://o2uk.co/O2CIG) , they should be able to help you with this, however, the usual answer is denial.

I've got an open ticket for the same issue with 02 Corporate support at present
Using Iphone Net Analyser the CCTV server firewall ports are reported correctly when connected through WiFi as 80,554,7681,8000
Connect through O2 4G and do the same test and every port shows open.
will see what they come back with

Have you done any packet inspection at all when connected via mobile to see what the response is to from the host / proxy. (you can do this via wireshark and using your phone as a hotspot)
Is this an Internet facing device or an Internal device?
What happens when you SSH / Telnet to the host on port 8000 and bare in mind port 8000 is not mean to be exposed to the internet, and should be behind a proxy as per the best practices.
This could be down to CGNAT on the o2 network, and how it handles the return traffic
