Today my mining gears couldn’t connect to the mining pool from CGMiner which using port 3333 and some port which were used for Cryptocurrency Mining.
First, I was suspecting that some application blocking the access to the port, but then I tried to switch the Internet Service Provider (ISP) from Smartfren to Telkom Speedy, and the results is CGMiner can connect to the mining pool.
So I’m back with Smartfren and run the OpenVPN, and then tried to connect to mining pool using CGMiner. Guess what? It’s connected !
This is the first time I met an Indonesian ISP that blocked the port for Cryptocurrency.
