In the HOME tab are there any errors?
In a sample working transfer (use a fedora download) under EVENT LOG are there any errors?
You mention DHT unconfirmed? Is this with a manual port forward from your router, or do you use Tixati setting for NAT/PMP ??
If you know how to use command windows these are three lines i ALWAYS use to check if my ISP FUBAR my connection/modem.
ping 192.168.0.1 (or 192.168.1.1 depending on your LAN IP)
ping 192.168.100.1 (or your modem IP address)
ping www.google.com
The First line checks your connection INSIDE the lan. among all your computers.
The Second line checks your ISP modem connection (if it froze or was compromised from mirai usually this hangs here with "100% failed" messages)
The third line checks if your ISP decided to forcibly reset/ null route your DNS which is the backbone of many torrent swarms (trackers).
You can check based on TCP/UDP also but that's a bigger issue.
FIRST THINGS first, can you get any upload on a leech (download) heavy swarm??
Second, should you have any issues with the DHT port (maybe you didn't re-enable the windows firewall exception, OR in your security software)?? I usually refresh my rule
a) on each upgrade of Tixati, just because. Many times software uses HASH to verify the program
b) if i install any other security software which may interact
Aside from those main instructions have you done through the
https://www.tixati.com/optimize/ guide to see??
Please reply below with more information or requests about specific usage or settings :D
