According to your picture (please remove the exif data next time if you want to stay private),
you are located in france and not iran.
What miner do you use, what firmware is on it, wich pool works with your miner?
I'm not in France. I am in Iran.
I think the data is sent from Iran to France and then sent to the destination, France is just a bridge for Iran.
My devices in farm are t2t, but I have m3 at home, m3 is for testing only.
However, I tested with the same t2t, but the pool is dead.
I checked at home with m3 and the connection was made for a while but the pool died again.
the firmware is latest version.
All pools except btc.com and antpool work with my miner.
European servers have always been better for me.
