a) Is Tixati added to Windows firewall exception list for both private and public network types (depending on how you connect to the internet)?
Yes.
Are there other firewalls or other security measures further down the network (e. g. on your router)? Can they intervene?
NO.
b) Does your ISP use NAT for its subscriber network?
Yes.
But I have been torrenting for last 10 years with this same company, so even after CGNAT I never had an issue with this. I am a Tixati user since covid.
Is it known for inhibiting user torrenting (mobile providers most certainly are, even if they don't announce it openly)?
NO.
High Speed Optical fibre cable FTTH connection.
c) Have you chosen a specific IPv4 interface in settings, or any/none?
No, everything is default in that regard. Have not tinkered anything.
d) What do DHT search request stats say? What do the graphs say about incoming/outgoing packets? How does it compare to previous behaviour? Do you see any data from DHT/torrent peers at all?
Attached screenshots.
It was all good till this suddenly happened.

e) Have you mis-configured something to block the Tixati port, and forgot about it?
Did not configured anything, everything is in default state. I use public trackers so I do not need to set-up Tixati at all, everything works automatically.
Go to settings, reset the DHT ID, change main network port, (stop the client to be 100% sure, wait for 5-10 minutes, then start again).
resetted DHT NODE ID, nothing happened after 2 minutes of showing online; it is back to online port blocked.
I have used BiglyBT and qBittorrent and both says NAT OK after 5 minutes or so. But, not in Tixati. As can be seen =

Even Tixati used to become online after 5 minutes or so, This issue is extremely sudden and I have used Tixati intermittently due to Xmas and New year vacation.
That's why I have raised the issue.
Windows 10, Tixati 3.42
