I am new a Grin and I tried to use Grin++ on Windows professional to receive both mining transactions and transactions from an exchange without success so far. To my understanding, installing Grin++ already opens the right ports but after not receiving payment from mining (and I vaguely remember seeing some error about a port) I opened ports 314-317 in my firewall (inbound and outbound rules) and forwarded them on my router to my PC running Grin++.
After opening them I bought some GRIN at an exchange and tried to transfer it to myself without success. Now I am at loss to what the cause is, especially since I see no errors whatsoever. I do not even know for sure if the exchange tried to send it since there is no way for me to validate what they are doing. Grin++ shows 15 outbound and 35 outbound connections by the way. Can anyone please send me a 1 Grin Satoshi so I can validate if Grin++ is working or point me to an exchange or tell me how to do a testnet transfer to my Grin++ for testing?
Any help or suggestions are very much appreciated.
