FTP Connection Woes

I'm having some unexplained FTP connection issues which I hope someone might help to resolve.
With my last ISP a FTP server I have been connecting to for many years suddenly stopped accepting my connections. I had my home security cameras setup to upload recordings to the server and on an occasion tons of footage was uploaded during a day. Just after this the problems begun - but I can't be sure that the event is directly related.
Here is what I have done to troubleshoot:
1. Contacted the host - who confirmed I wasn't blocked
2. Tried connecting to the server on another PC on my network - also unable to connect
3. Tried disabling all firewalls and anti-virus - no beef
3. Tried connecting via tethering of my phone's data - I was able to connect!
This all led me to conclude that I must be blocked at the ISP level. Since I was due to leave the previous ISP I guessed that all would be resolved when I joined Plusnet. My account and service was activated this week and lo and behold I have the same issue persists.
I know that:
1. My device isn't blocked (connection via phone works)
2. The ISP isn't blocking me : (2 ISPs same result)
3. The host is not blocking me (phone connection works)
It seems that I am being blocked at a higher infrastructure type level - if that is possible?
The FTP connection is SFTP and the error message is:
Error: FATAL ERROR: Network error: Connection timed out
Error: Could not connect to server
Other FTP connections work fine! This problem is driving me crazy and I've run out of ideas. Any suggestions?
Thanks!

Just discovered that switching to FTP (:21) enables me to connect. So why would :22 be blocked and where?

Yes I have tried disabling the firewall in the PN router and also adding my device to the DMZ. This is a real mystery!

Where is it in the member centre - I am logged in and cannot see any firewall options?
